Level 30 Gruul with Rank 5 in all 3 skills
Equipping him with Dragonclaw Fists at rank 3 only apply a +5 attack buff when a dragon is present despite it listing a +10 attack
Persists through multiple combats and unequiping the item and reequipping it
I did upgrade it and Dragonclaw Fists at rank 4 does work correctly and is applying a +15 attack buff to Gruul when a dragon is present. It’s just the rank 3 that is bugged.
