I know you said Anu leveled up, but it's not listed under my Trainer Tab.
Also, quick questions: If I ever did use Rage (which Anu learned last level) or other removes like Power-Up Punch would those have any effect in this RP? Likewise, how would multi-hit attacks function?

Ah okay.
So like in that last fight, it would have been: Anusobeket gets a -50% modifier, thus effectively canceling her STAB for the next turn?
Sounds good, boss!

It won the roll by 16. By these new rules, it may have won the roll by even more. ... BUT it would not have done anything to your Totodile THAT turn.

Okay, well now you've lost me. You say that the effects won't take hold until the next turn, but then you also say the roll would've been even more in the Larvesta's favor..? So it effects its roll on the same turn, but effects my roll on the next turn?

Edit: sorry, didn't mean to send the message yet
...
Does this also mean that moves that Raise a Stat and Deal Damage like Power-Up Punch would deal damage and just add the effects on the next turn only then? Or would it be like healing moves and be cut 50/50?

What about Multi-Hit attacks?

@Balthazar007
That Phanpy's rolls was still ridiculously higher than mine, but just so you know: it shouldn't have gotten STAB for Defense Curl. Phanpy actually never learns any Ground Type moves for some reason.

From now on ... moves that are purely designed to lower or raise a stat will gain a 50% boost on their roll ...
