Sword Mastery Tier 3 - 5% Damage Increase?

[Val-Tur]

When I activate Sword Mastery Tier 3, I can clearly see the extra 5% HCI/DCI, 5 Str. But I cannot see the extra 5% DI. Is it actually there?

It’s a bug, it’s supposed to read Damage modifier not damage increase.

Just a reminder:
Modifier is what slayers and EEO do after your 100% from gear boost.

For bosses that have no slayer you are much better off with modifier instead of increase. Very nice for things like roof or Niera
