Many Garen Players are sometimes curious if investing in the Offensive Masteries regarding its interaction with Demacian Justice. I did some quick Math to see the additional Damage granted to Demacian Justice in the Offensive Masteries with Arcane knowledge, Executioner and Havoc.

Combined, we have 10% Magic Penetration, 6% additional damage to targets below 40% hp and a total of 1.5% additional damage. As an example, I worked off a target with 900 hp remaining of 3100 health and assuming they have 100 MR (50% Magic Reduction exactly) and checked the differences in damage of a Non-Offensive Masteries Garen and Offensive Masteries.

40%(2.5 health missing is 1 dmg for DJ) of 2200(Hp Missing) is 880+ 525= 1405.

Without any Offensive Masteries, the damage comes to 703.

With Offensive Masteries, 21 (3% extra from 100 MR reduced to 90) + 43 (Executioner) and 11 (Havoc) gives you a grand total of 778.

Overall, an extra 75 damage. In conclusion, the Offensive Masteries, at least in regards to Garen's Ultimate Demacian Justice, makes a very minor difference regarding damage.
