This just in: Cementoss's cement structures are now affected by damage boosts from tuning. Last season they were not.
Pic related is his alpha, but I've tested his beta and gamma as well and they both receive the appropriate buffs, too. Big news for Cementoss players.
I'm going to test whether the same fix also applies to other attacks that create secondary effects, like Endeavor's beta and Momo's gamma.
