Question on how focus effects decay... For say improved healing III it says it decays 5% per level over lvl 60. Does that mean for lvl 65 spells that focus is rendered completely ineffective because it goes from max 20% at lvl 60, 15% at lvl 61, 10% at 62, 5% at 63 and then 0 for 64+ OR does it mean that there is a 25% reduction in its overall effectiveness at lvl 65 (5% a lvl for 5 levels) so that the 20% max becomes 25% less effective or reduced to a max of 15% at lvl 65?
For scholarly reasons, the post-AK implementation was the later example you provided. But as RW indicated, we have no focus scaling when you exceed the level of the focus. Fortunately end-game Luclin focuses go to 65 so it’s not a big concern once you get into VT.
