A great number of legendary materials are, for a lack of a better word; useless. Utterly useless. Which ones, you might ask? The Greater Inscriptions that grant your creature a permanent buff. Why are they bad? Because they’re outshined, royally, by the creature ability materials.
Greater Inscription of Bezerking: Your creature has berzerk.
Berzerker Infusion: Your creature has berzerk and recovers 10% health after attacking.
I suggest plainly removing these materials from the game, as currently they’re insta-rerolls at the enchanter’s, and nothing more. Likewise, I couldn’t help but notice that there’s no (rare) inscription for the Arcane buff, despite there being one for both Magic and Proffeciency, both of which are quite similar to Arcane in that one adds a lot of oomph while the other is caster specific.
