Vyr Chantodo Rune selection mismatch with max elemental% on gear causes your Chantodos damage to not benefit from that elemental% damage.
In the video, I apply 40% cold element to my gear, and test first the damage of chantodos without any other bonuses. My test setup was at around 10K int, 5% CHC, 50% CHD.
Chantodo WoD Damage with Slow Time Archon Rune selected and 40% Cold:
17,166,352
Chantodo WoD Damage with Pure Power Archon Rune selected and 40% Cold:
12,261,809
12,261,809 * 1.4 = 17,166,352.6
Vyr 2 pc gives all runes but doesn't provide the same damage for Chantodos if you select the wrong rune. This is a bug.
It should be fixed so that players can't possibly make this mistake, and additionally, so multi-element chantodos setups can have more of a fighting chance by allowing both of their elements to benefit from the different elemental percentages applied to their gear.
