I'm really happy you're making a leveled mod, after playing some time, I noticed some bugs:
When overleveling then spending my status points, it's common for my character to have negative status points which both make me lose new level stat points and also make me in the moment weaker.
I don't know if this one is Tmodloader based but moon lord does like 1 damage but the true Eyes of Cthulhu basically 2 shot you.
It is easily a problem that you can reach crit chance caps without ever spending status points on luck, either make the stat more useful by nerfing specific stat crit gains, or add it an additional feature to outweigh it, right now luck only affects 1 RNG mechanic, but the rest are unchanged, maybe mess with those.
Also, I found the EXP progression from the Regular RPG mode to be too grindy, I had to kill overleveled enemies for about 4 hours to get to at least 150(after raising the EXP rate to 4, which is the maxium). Is the max EXP on regular supposed to grow after level 200%? I found it to be capped at level 100 to about 106 million but after level 200 it's at like twice that value.
At last, I don't think the damage multipliers coming from prefixes are stacking properly, adding an accessory prefix barely increases dps (meaning the damage bonus is treated as an addition rather than multiplication), but seemingly weapon prefixes does scale multiplicatively.
I'm looking up to this mod to play, really a fan of the N terraria series.
