Ky's Blade Fall + Blade Blast Slinger / CoC Assassin Leaguestart to Endgame

Bladefall Blade Blast Spellslinger Assassin is a super fast incredibly strong all-around character that can be taken from day 1 and scaled all the way to pinnacle Ubers with ease.

This build is 1 button from start to finish with no need for piano-style gameplay.

We start off in act 1 with Blight Essence Drain Contagion setup, which we stay on through to Act 3. After killing Gravicious in the barracks in act 3 is when you unlock Bladefall and it is here we can fully transition into a Spellslinger setup.

DO NOT LEVEL YOUR Arcane Surge Support THAT IS SOCKETED INTO YOUR FROSTBLINK, IT WILL LOSE YOU TONS OF DAMAGE IF U DO.

DO NOT SWAP TO Spellslinger UNTILL YOU HAVE Eldritch Battery ALLOCATED AND AT LEAST 250 Energy Shield

This will be around level 36!

Once into a Spellslinger setup look for wands with good FLAT damage on the wand such as +#-# added Physical/Lightning/Cold/Fire damage ( phys is best ), but any line is a huge amount of damage. You can also craft on % Inc physical damage on the crafting bench for a huge damage boost.

In act 4 you will allocate Eldritch Battery. You need to have an ok pool of Energy Shield to use this keystone, so make sure you have around 150-200 AT MINIMUM on your gears total. You can allocate Essence Surge early on to help with this.

Look to swap into Mind Over Matter at level 70-75ish. You should have AT MINIMUM around 3.5k life and 1k Energy Shield before doing this. Ideally around 1400es. *THIS KEYSTONE SHOULD NEVER LEAVE YOUR CHARACTER EVER AGAIN ONCE ALLOCATED* Please do not Swap off it in the final tree without a Cloak of Defiance ( with +2 AOE Gems Corruption ) or a Skin of The Lords ( Mind Over Matter Variant .)

Light of Divinity is a good cheap early annoint.

Recommended to Help Alira in Act 2 & Swap to +1 passive point later.

Our asendency order will be:
Unstable Infusion 1st
Deathmarked 2nd
Mystical Infusion 3rd
Mistwalker 4th

FAQ

Spectres

Perfect Pain Artist / Perfect Forest Warrior.

Other Options to consider Depending on Circumstance:

If you are post-Necrotic Armour ( unique chest ) and do not have another source you can get Endurance charges with a Perfect Warlord.

Perfect Forest Tiger is very expensive but nice for speed. Although I found its frenzy charge generation not reliable enough to remove mark mastery as I hoped I would be able to.

Animate Guardian Setup

Weapon: Early Either a Dying Breath or Sign of the Sin Eater + 5% life gain on block shield. Sin Eater doesn't do anything if you have your Stormshroud in, but not many good alternative 1 hander's I could see.
Late Weapon - Kingmaker.
Body: Gruthkul's Pelt
Boots: Windscream
Gloves: Rare Glove with Despair on hit and as much res as possible.
Helm: Early - Leer Cast Late - Crafted Rare Helm with -9% Chaos Res to Nearby Enemies ( Hunter Mod ) with res.
Animate Guardian's Default res is 40% for all elements and 20% for chaos. Its very important you cap his res on elemental and hopefully 1 line of chaos if possible.

Common Mistakes

Do NOT remove highwayman until you have either 0.4% life leeched as chaos ( a delve ring mod ) or an eater of worlds 0.3+% of chaos damage leeched as life eldrich implicit on your gloves. You currently have 0 life leech. So for now take off your ming's and put on highwayman untill you get a replacement.

Make sure you always have Overwhelming Malice allocated on one of your cluster jewels once you have swapped into Cast On Critical Strike Support.

You should ALWAYS have Hit's Cannot be Evaded crafted on your foil, or you will be missing a ton due to no accuracy rating.

Make sure to check your tree after changing between setups for leftover points.

Its best not to have a life modifier on your chest so you can take the life mastery for 15% increased maximum life.

Taking the full leech wheel right next to eldrich battery early on along with the +5% instant leech mastery, can help your recovery tons if ur low on damage.

Once you have endurance charge generation on your chest make sure to change your charge mastery to 100% increased charge duration for perma-uptime.

Flask suffixes are a huge boost, you should have evasion rating, movespeed, crit chance.

At all stages of the build every piece of gear should have a t1-2 life roll on it, with as much es and evasion as possible coming second in priority.

If you feel squishy make sure you have the above, your suppression is capped, and you have a life:energy shield ratio of ideally 3:2. You should NOT bring your life down to achieve this, but look to raise your energy shield if you are off.

Do not overlevel your Cast when Damage Taken Support. It should be at level 5-6 with steelskin at a level low enough to be procced by it which should be around 13-14 ( check the level requirements ).

Also make sure your flesh and stone is set to sand stance.

This build is much tankier than the face value numbers lead it to be. If instant leech presented its recovery in the same way that Aegis Aurora did the EHP would be in the 300,000 to millions range, although this does require you to have something to hit. Make sure to follow these guidelines and deaths should be extremely rare.
