Terrarian
I had issues with those too and also Celestial Bow. Now they're gone which is a nice thing to see.Well I fought the fallen beholder and the lich at the same time, with terrarium armor, a lot of draconic magma staff summons, and I used the soul cleaver/ (I was trying to produce a lot of lag, by getting a ton of dust on screen) It appears that the new tmodloader update fixed a lot of the lag.
