Possible Pursuit
Calcinator is an item that rewards pathing your run to optimize the quantity of Transforms. Similar to Pygmalien and his Damage-stacking builds, you need to pursue it early in order to stack up enough value to contest the mid to late game.
While the Mandala Transform events will help, ultimately you'll want an early
Potion Distillery, or a couple of
Catalyst generators like
Alembic to make it worth your efforts.
It's okay to use
Calcinator within the first few days, but if you don't find reliable Transform by day 4-5 you'll likely need to pivot to something else. Visiting Mandala can only get you so far.
Note: This build can also be attempted with
Retort instead of
Calcinator. They both fulfill essentially the same role, but do keep in mind that
Retort is generally a bit slower (Burn ticks faster than Poison).
Calcinator
Every Reagent Transformed contributes a pretty significant amount of Burn, and the rate gets really good at higher tiers so be sure to upgrade as soon as possible.
You'll also need to ensure you have an ample supply of Reagents. Transforming other items doesn't count, so be sure to purchase whatever Small ones you find.
The
Chunk of Lead provided at the start of each day will help, but there's still the potential of up to four Transforms per day. Look to purchase extra Reagents to make sure you always have one available when needed (although don't skip priority events like Mountain Pass which can grant XP).
Kripp enchanted his
Calcinator with Obsidian to give it a huge Damage boost. Given that this is the sole threat of the build, boosting its offense is a great choice.
Palanquin
Palanquin is an excellent supporting piece for
Calcinator, providing two things that greatly support single-item builds; Crit Chance and Cooldown reduction. Since
Calcinator is the primary focus, the most important thing is increasing its Damage potential to ensure every activation counts.
Where it also shines is by helping ensure the second cast comes much quicker. Assuming you can Crit the first time around, the following time will be much faster, and if that's not enough it will continue to accelerate if the fight goes longer.
If you can, look to acquire additional sources of Crit Chance to up your rate even more. While 50% will do a decent job, boosting it a lot higher will help avoid those times where luck isn't on your side.
Additional CDR
Hourglass and
Star Chart help provide even more Cooldown reduction for
Calcinator.
Star Chart also has the added bonus of extra Crit Chance, although obviously not a common pickup as a Vanessa item.
Feel free to flex in whatever utility option(s) you find, with the main goals being to accelerate and enable
Calcinator, or add another layer of defense/disruption.
