what is heat nherit
Heat inherit is a hidden mechanic that that is caused by the infinite refreshing status duration of the heat proc.

The elemental bonus and faction damage bonus from heat Dot is determined by the bonus of the first stack of heat DoT. It is named 'heat inherit' as the later heat DoT inherits the damage bonus from the first stack.

Heat Inherit Calculation is as follow:
The first stack of the heat proc from the first weapon have X amount of bane, Y amount of heat mod, its base damage is Z;the second weapon have M amount of bane, N amount of heat mod, its base damage is K
The damage of the first stack of heat dot will be:Z x (1+X) x 0.5 x (1+Y) x (1+X)

The second stack of heat dot(from the second weapon) will be:K x (1+M) x 0.5 x (1+Y) x (1+X)
and now both damage will be combined, the damage from the second weapon has inherited the bane and the heat bonus from the first stack.

For example
Using Zylok with 60/60 heat mod + Primed Heated Charge + Primed Bane as your first stack weapon (55%bane+225%Heat)
Using Twin Basolk with 60/60 heat mod + Normal Bane(30%Bane+60%Heat)

The damage of the first stack(from [Zylok])：140 x 1.55 x 0.5 x 3.25 x 1.55=546.56875
The damage of the second stack(from [Twin Basolk])：210 x 1.3 x 0.5 x 3.25 x 1.55=687.61875
Bonus melee damage from dual swords default stance(300%)：687.61875 x 3=2062.85625
theoretically combined damage is 2609.425，In-game damage dealt is 2612

Notes:

• [Shattering Impact] can be swapped with more attack speed or s riven if you are utilising an armour strip ability such as Ash's seeking shuriken augment

• tysis primer: https://overframe.gg/build/198499/

• utilising heat inherit will increase damage by around 3 times, from an average of ~55,000 with a normal heat build (based on 1 Heat DoT proc) to ~150,000 (based on 1 Heat DoT proc)

• for even more damage you can utilise a weapon with like the [Skana] with iron phoenix as you gain an additional 300% melee damage from the stance
