I feel that the current OP items are currently just a little too OP. It isn't as much fun when all of the items are basically OHKOs when thrown.
I think the first set of items you put out in the previous thread hit a much better level of OP.
That said, I'm still loving them, but I feel they should be tweaked a bit.
The fact that the fairy bottle deals 100% when you throw it is hilarious, but maybe reduce the knockback so it isn't a OHKO below ~40%
For the star rod, maybe instead of making it a OHKO when thrown, ramp up the hitlag to some absurd amount so the opponent is frozen in the air for a few seconds allowing for a strong attack.
The fire flower is really amusing to use when an opponent has really high damage (around 250%) because they start just bouncing up and down on the floor. Maybe up the base knockback a bit so it happens sooner? Otherwise, it's perfect.
The drill and empty drill do way too much damage IMO. ~70% would probably be better.
I think the rest of the items are perfect as is.
Please don't take this post the wrong way. I really like what you've done so far and I understand if you are happy with how them items currently are and don't want to change them.
