Rugnor Goldgleam better than Pyxniel?
Rugnor Goldgleam is a void epic needed to fuse Pyxniel.
He offers Leech on A1, strong versions of Decrease Defense and Weaken on A3.
Leech is perfect against both Doom Tower Spider bosses. Single target Decrease Defense and Weaken are what you want on bosses. Clan boss too, if wierd turn meter A2 can be tamed.
Pyxniel looks like a champ for Frost spider teams. Rugnor may fit those teams better.
Also, Pyxniel is High Elf. The easiest faction war to complete because of Arbiter. Rugnor is Dwarf, one of the most difficult factions.
Rugnor is a void epic, so he is hard to get from shards too. He is not available as a tournament prize, therefore only one copy can be fused. Is it wise to sacrifice him?
PS. Most of "why he is good" stuff comes from MurderInc video.
