Overview
In Path oF
Exile (PoE), the Molten Strike is a mechanically interesting
skill that can have good damage scaling. This damage comes from
some complex interactions that are not handled in the ingame
tooltip or by tools like Path of Building (PoB). This calculator
complements PoB to help users estimate their true single target
DPS against isolated single targets.
To use this calculator, enter appropriate inputs in all the
editable input fields. For more details on a given input or
output, click on its description or data field and this help
section will be replaced by details about that line.
This calculator has been updated for the 3.16 patch of PoE.
Known Limitations

Longshot: Longshot is not currently supported.
This is because it would require a lot of extra user
input so we could correctly account for diminishing
returns.

Nonnamelocked melee hit locations: This
calculator does not estimate the damage boost from using
Hydrosphere with Ancestral Call, Multistrike, etc. Those
potential damage boosts are highly dependent on the
exact placement of the sphere relative to both the
player and the boss, which is being namelocked, etc.
They can even make your DPS worse. Adding those
calculations would add a lot of complexity and possibly
slowness to the calculator. See the the iPython notebook
in the github repository for an example of how we've
done more complicated estimates for nonnamelocked
situations in the past.

Circular shapes: This calculator assumes both
bosses and balls have circular hitboxes, but past
statements from Mark_GGG suggest that some or all
hitboxes are actually squares. Additional experiments
are needed to verify this and to determine how the
squares are rotated. If the rotations are random, then
this calculator's approximations should be close to
correct.
Version History
 20211120: general overhaul

Added a dynamic chart showing the damage
rangebased multipliers as a function of ball
landing distance from the melee hit location.

Greatly simplified the calculator, now relying
on PoB to supply the projectile counts, ball
AoE, and ball landing zone information. PoB does
a more careful job with rounding, so this may
change the DPS estimates a little bit relative
to the old calculator.

Made the default average hit chance be 100%
since that's now common. Also, changed the
assumption that we need to use the min of melee
and ball hit chances instead of just the ball
hit chance since ground targeting was removed
from the game and it's easy to prove that
missing a melee hit means no balls sprout.

Made the projectile travel distance be blank by
default since that's what both PoB and
poe.ninja have been (correctly) doing
for a while.
 20200618: updated for patch 3.11.
 The min travel distance is now 2 instead of 6
(was apparently incorrectly 5 in the calculator
before that).
 The default max travel distance is now 25
instead of 20.
 Wildfire has been completely reworked.
 Projectile speed modifiers now affect the travel
distance.
 Removed the "Effective Ancestral Call Damage
Multiplier". It hasn't worked for a while. Depending
on how chain works, we may add some calculations for
it in the future.
 20200204: Fixed the default number of balls (4, not 3).
 20200201: Molten Strike has been nerfed in many
ways during the last few leagues. This calculator
has been updated to account for those nerfs. Note:
if you've bookmarked a calculation, it'll still use the
old numbers (except for point blank).
 The new default is 1 wildfire jewel instead of 2.
You can still put in a different number if you
want to compare against DPS before the cap
was lowered (with no legacies).
 The default number of additional projectiles
from the helmet enchant has been lowered to 2.
Legacy +3 enchants still exist on permanent
leagues so you can change the value back if
needed.
 Point Blank's max more and less multipliers
are now 30% instead of 50%.
 The Ancestral Call trick no longer works,
so its default multiplier is now 1.0.
Additionally, it's common to download PoB codes from
poe.ninja, and it seems to use a Point Blank radius
of 10, so that's the new default, instead of blank.
As before, when a radius is put in PoB, this calculator
has to reverse out those effects then recompute the
correct radius interactions internally (instead of
just doing the correct calculations without needing
to reverse out slightly incorrect PoB calculations).
 20181101: improved how point blank and farshot
multipliers are presented. Also made a few other minor
improvements to help strings, internal comments, code
clarity, etc. Added a limitations section to the main
help string.
 20181029: added far shot support
 20181028: converted to a Javascript implementation.
this version supports bookmarking, has more intuitive
inputs that work around PoB bugs, adds more point blank
inputs so people don't doublecount it, adds an
Ancestral input, adds convenient inputs for automating
the ball count calculations, lots of documentation, etc.
 20180728: added usage notes (thanks xhul for the
feedback!)
 20170715: fixed projectile spread distribution based
based on info tracked
down by reddit. Also added a graph for finding the
optimal AoE modifier.
 20170529: original Google Sheets version
