Deathfire Touch is a tier 6 Ferocity Keystone mastery.

Notes

•  Deathfire Touch is a on-spell effect and will only be applied to instances of ability damage.
• The damage from this mastery does not trigger itself nor other spell effects.
• Multiple instances of damage will refresh the duration but do not stack.
• The duration of the effect for damage over time abilities is: DoT's duration + 1 second.

Comparison to  Thunderlord's Decree

While  Thunderlord's Decree offers a serious boost for bursting power,  Deathfire Touch excels in prolonged skirmishes.

One Hit

When a mastery is triggered only once,  Deathfire Touch is superior to  Thunderlord's Decree in following scenarios:

• Unit-targeted and damage over time application: 1146 AP or 1146 bonus AD is needed to match the damage of  Thunderlord's Decree. As most DoT abilities last at least 3 seconds, they share the same damage as single target application i.o. four seconds and thus eight cycles of damage.
• Area of effect application: 7040 AP is needed to match the damage of  Thunderlord's Decree.

In every other instance  Thunderlord's Decree does more damage than  Deathfire Touch as it scales better or at least as well.

DPS Comparison

•  Thunderlord's Decree has minimum of 15 seconds static cooldown that can be converted to produce 12 (+ 2% bonus AD) (+ 0.667% AP) damage per second.
•  Deathfire Touch can spread its damage potentially the whole time with rate of 2 (+ 11.25% bonus AD) (+ 6.25% AP) damage per second.
• This means only 108 bonus AD or 162 AP is needed for  Deathfire Touch to do more damage than  Thunderlord's Decree if it can be used continiously.

Threshold

Sec	AP	Bonus AD
5	800	647
6	611	448
7	492	340
8	410	273
9	351	227
10	305	194

As the previous examples illustrated, the longer the fight lasts the less AD or AP is needed for  Deathfire Touch to be superior compared to  Thunderlord's Decree in sense of damage done in total. Table below gives some figures to give feel what is the threshold for bonus attack damage and ability power to  Deathfire Touch to do more damage than  Thunderlord's Decree at level 18. Before level 18 these thresholds are roughly 10% lower per level as base damage of  Deathfire Touch does not increase per level.

Trivia

Last updated: June 18, 2017 – V7.12

• The largest amount of damage any champion can deal with one application of  Deathfire Touch is 1153.6246765163 magic damage over 4 seconds, being a level 18 Jhin.
• From the trivia section of attack damage, we extract the value 2619.165947814 which is the highest amount of AD possible on Jhin.
  • From that amount we subtract Jhin's base AD of 138.9, we obtain 2480.265947814 bonus AD.
  • On top of that we count the masteries and buffs increasing his AP, we obtain 85.8 AP (( 40 +  15) × 1.56 = 85.8).
• Jhin can damage his target with either Deadly Flourish or Curtain Call, both applying a single target damage. One application of  Deathfire Touch damages an enemy for 4 seconds for a total of:
  •  Deathfire Touch damage = 8 (+ 25% AP) (+ 45% bonus AD).
  •  Deathfire Touch damage = 8 + 21.45 + 1116.1196765163.
