Unvar’s Hegemony has this line : 2% Chance per Intelligence for +22% Elemental Penetration with Two Rune Invocations
However, when testing with a character with 84 intelligence, I did not get that bonus for penetration.
All tests were done on dummy with Unvar’s Ice Glyph (Heo Heo Runic invocation), 84 int, and no pen other than the Runic Invocation node “Elemental Lore” (1 pen / 3 int = 28 pen)
Without “Elemental Lore” and without Unvar’s Hegemony (so with 0 pen), I did 327 dmg.
With “Elemental Lore” and without Unvar’s Hegemony (so with 28 pen), I did 419 dmg, so exactly 1.28 multiplier, as expected.
With “Elemental Lore” and with Unvar’s Hegemony (so with 28 pen and 2*84=168% chance of +22 pen), I did 419 dmg still.
=> Unvar’s Hegemony doesn’t seem to apply his elemental pen
I did LOTS of test and ONCE, noticed a 490 dmg, which is exactly the 1.5 multiplier expected from pen if Unvar’s Hegemony applied his bonus penetration.
=> In the end, it seems to me Unvar’s Hegemony does not scale his chance bonus pen with intelligence, and only applies a flat 2% chance, which I strongly believe is a bug.
