What you were expecting to happen, and what actually happened:
The screenshot shows 61 damage, +90 damage from boost: Orpheus has 22 mana filled, my Hero has 20, Infernus has 24, Stonehammer has 24. That’s 22+20+24+24 = 90 boost damage, which is what it says under the boost calculation. And the text in the description says “boosted by ALL ally Mana.” Orpheus also has Arcane trait which gives him +1 Magic when an ally casts a spell. And the Delve also gives him another Arcane trait, for +2 Magic total when he casts. This counts his own cast too, before he casts it, so the total damage will be 61+2+90 = 153.
Luna has 168 health. So she should be left with 15. But as you can see in the follow-up screenshot, she only takes 131 damage. Let’s work it backwards then…
131 - 61 (initial damage) = 70 - 20 (Dawnbringer) - 24 (Infernus) - 24 (Stonehammer) - 2 (Arcane traits) = 0 … uh, so, I guess that 22 extra damage from Orpheus’s own mana means nothing?
The problem of course is that Orpheus text SAYS it is boosted by ALL mana, and the boost also counts everybody’s mana, including his own, but the calculation only happens after you cast the ability, which drains his mana to 0, so you lose the 22 expected damage.
If we’re going strictly by his ability’s wording, he should be dealing 22 additional damage with every cast. If his wording is wrong, then it should be adjusted to say “boosted by all other ally’s Mana” and the boost calculation should be corrected to reflect that as well, because the damage he actually does already does that.
How often does this happen? When did it begin happening?
Every time.
Steps to make it happen again
Just cast his spell.
