Trinity Firestorm Stormweaver - Full Endgame Guide (T16+)

This Stormweaver build focuses on using all Three Elements (Fire, Cold, Lightning) and utilising the new Elemental Infusion System to become a True Tri-Elemental Caster Build.

This build also uses a New Zero Energy Shield Defence Tech that makes you Incredibly Tanky for a Sorceress utilising a number of the new mechanics made available in 0.3.0, so if you fancy playing somything a bit different this will be a lot of fun for you!

This build will was based upon an SSF Levelling run using the Levelling guide so be sure to check this out if you are not yet at Mapping.

The Endgame build is based upon a mixture of Self Found Gear and Trading which hasn't been too expensive because a lot of this build is playing into Techs that aren't common knowledge right now.

If there are any Coming Soon areas in the guide, I will get round to updating those ASAP but if you have any questions be sure to reach out through the various methods of contacting me linked in my profile above.

NOTE: This build is still a work in progress. If you have any questions about the build, feel free to jump in my Discord and ask me questions directly.

I'l be live streaming most evenings (GMT) so this is a good time to come ask me questions directly!

Build Rotation

This build has an Interactive Play Style and requires you to Combo Your Skills instead of being a One Button Build. If you like builds that have a more Methodical Approach whilst still being able to blast then this build is for you. The following is the recommended rotation:

Repeat To Keep Up

• Place Orb of Storms for Chain Freeze Buildup and Infusion Generation.
• Place Frost Bomb for Elemental Exposure Buildup and Infusion Generation.
• Place Sigil of Power for Extra Damage.
• Place Elemental Weakness to Multiply Our Damage Further.
• Cast Firestorm frequently enough so it's Always Up.
• Cast Fireball if enemies are surrounding you for Extra Trash Clearance.
• Apply Living Bomb as often as possible for Big Damage and extra Infusion Generation.

It might not be possible to keep this entire rotation up if in a sticky situation so the main things to keep going are at least 1x Orb of Storms, 1x Frost Bomb and your Firestorm to try Freeze surrounding enemies and get back on top of the combat situation.

Use your Dodge Roll actively to get our from being overrun if you are struggling to Freeze the enemies which is your main source of Crowd Control besides Temporal Chains for Slowing The Enemies Down.

Note: This is being actively updated so I will aim to flesh out all the missing areas ASAP.

Skill Info

Frost Bomb is early on is quite a useful skill for clearance and an extra source of damage. Later on it tails off though so we end up using it for the many other useful attributes it brings to the table. It provides a base 20% Elemental Exposure and is the only skill that can provide up to 50% Elemental Exposure based upon how many pulses hit your targets. This is a great way to gain an extra source of Damage Multiplication and acts as a hidden damage source. The secondary benefit is that each time a Frost Bomb explodes it grants us a Cold Infusion or a Random Infusion when Elemental Equilibrium has been taken which drastically improves our Infusion Generation. This in conjunction with Overabundance II and either Spell Echo or Spell Cascade means we can exceed the +1 Limit and multiply how fast we Apply Elemental Exposure and Generate Infusions.

Sigil of Power

Sigil of Power is made available through equipping a Chiming Staff in our Weapon Set 2 equipment slot so it doesn't require a free Skill Slot. It boosts our damage drastically which is very useful against Harder Single Target Enemies especially Boss Fights. The size is increased through Increased Area of Effect passives, Jewels and increasing the quality of the Chiming Staff to 20%, giving a +0.8m size increase. The duration is increased through the use of Increased Skill Duration passives allowing for durations upwards of 30 seconds+ in conjunction with Prolonged Duration II support gem.

In the End Game the aim is to get the Sigil of Power to last as long as possible with a size that is useful in combat situations where you have to avoid big attacks, giving options on where you can position yourself and still benefit from this huge damage boost. Clever use of Weapon Set passives allow us to unspec non-essential damage passives from Weapon Set 2 so we can allocate these points into Increased Area Effect and Increased Skill Duration clusters while allocating the damage nodes back to Weapon Set 1 to avoid any damage loss on our damage skills.

Mana Defence

This build does something wild and takes a Zero Energy Shield approach by taking Eldritch Battery and converting All Energy Shield To Mana. This can grant us a much higher Mana Pool at the cost of Doubling Our Spell Mana Costs.

It's worth noting that After Taking Eldritch Battery you really need to have a minimum of 1500+ Maximum Mana and 800 - 1000 Maximum Life for this to start to work, so please bare this in mind.

The thing about the Stormweaver is they added in their Ascensions access to 20% Damage Taken From Mana Before Life and many other ways to gain access to this stat in the Endgame Loop.

We don't want to take 100% Damage Redirect To Mana because this would make it so we run out of mana and can't cast. What we can do though with the help of the new Infusion System is create a system of sustain that is similar to what the Old Grim Feast used to be like for Energy Shield but for Life & Mana.

There are some New Notables that are exceptional for this setup and make it viable. For Mana consumption we can take Efficient Casting and Efficient Killing for Huge Mana Efficiency and 4% Mana On Kill. We can also take the newly added Vigorous Remnants and Arcane Remnants to grant us 3% Life and 3% Mana when Collecting A Remnant. The important thing to note here is that Infusions count as Remnants the same as any other Remnant you generate such as Mana Remnants. This can provide an INSANE amount of sustain which we spread mostly into our Mana Pool but allow some to go to our Life Pool so that we can still benefit from the Life On Remnant Collection and you coud even add some Life On Kill to the build as well to help with this through the use of Cannibalism I for example.

Mana Remnants is taken to generate us a huge amount of Remnants granting us a lot of Mana Sustain. This can be doubled in effectiveness using the newly added Empowering Remnants as well as getting access to 40% More Effectiveness from Remnant Potency III.

We're also generating a Metric Ton of Infusions which by casting Firestorm frequently enough will Consume one of each Infusion allowing us to pick up more in the process. Each Infusions we pick up grants us all the same Sustain Benefits that any other Remnant does so this doubles down on increasing our Effective HP.

As you manage to get your Mana Pool higher and as a result your Mana Regeneration a lot higher, you can look to scale a Higher Percentage of Damage Redirect To Mana. To start with I would recommend aiming for a 70% Balance scaling up towards an 80% Balance once you're nearer 3000 Maximum Mana and 500 Mana Regeneration.

The current known sources of Damage Taken From Mana Before Life include:

• The Ascension Node Force of Will. (Max 20%)
• Mental Perseverance Passive Node. (Max 10%)
• Lucidity Passive Node. (Max 16%)
• Chakra of Thought Passive Node. (Max 16%)
• Adverse Growth Passive Node. (Max 8%)
• Abyssal Suffix Modifer on Body Armours. (Max 20%)
• Abyssal Suffix Modifer on Amulets. (Max 20%)
• The Greatwolf's Rune of Willpower Body Armour Socketable. (Max 20%)
• Sapphire Jewels (Max +4% per Jewel)

Mana Stacking

Mana Stacking was nerfed quite a bit in Patch 0.2.0 but with the new changes in Patch 0.3.0 we are again able to make use of the Eldritch Battery key passive which became basically unusable before. This allows us to Convert All Base Item Energy Shield to Mana allowing us to build up a much bigger Mana Pool.

It's worth noting that the larger your Mana Pool becomes the higher your base Mana Regeneration becomes since it's based upon a a percentage of your Maximum Mana.

Not only does Stacking Mana become the majority of your Effective HP Pool, it also scales your damage by taking Arcane Intensity which provides 3% Spell Damage Per 100 Maximum Mana. This is particularly valuable once you get to 1500+ Maximum Mana. It's also worth noting that because Mana Remnants allows us to Overflow Our Mana it grants us more damage when this is the case, and we aim to be in this situation as frequently as possible
