Is this confirmed on PTS to have a damage cap at CP 990 now?
ZOS quoted 1560 as the maximum for vertical progression in the patch notes. That includes more than damage, though.
They don't seem to be touching slottables, so that's still 4x50 = 200 in blue alone for that (600 total CP).
20 for Precision
20 for Tireless Discipline/Eldritch Insight
20 for Blessed
20 for Quick Recovery
20 for Hardy
20 for Elemental "Defender" (apparently no one at ZOS got the memo that they renamed this to Elemental Aegis)
20 for Preparation
20 for Piercing
still 40 + 30 for Battle Mastery/Flawless Ritual and Mighty/War Mage (according to ZOS' math)
For all damage-dealing passives in addition to the 4 slottables, in either stam or mag, with no healing or mitigation passives, you will need 330 blue CP, or 990 total
For all passives with the 4 slottables (including healing and mitigation), but only in either stam or mag, you will need 430 blue CP, or 1290 total
For all passives with the 4 slottables (including healing and mitigation), in both stam and mag, you will need 520 blue CP, or 1560 total (ZOS' quoted max)
