I've been doing calculations on Doram's ASPD, so I figured I'd share it with you guys, since I didn't find it written anywhere.
Base barehanded ASPD of 156.
-20 ASPD with rod equipped
-7 ASPD for shield equipped
So equipping say, a mad bunny will make it -4 instead of -7. All other ASPD calculations are as normal.
Use the standard ASPD formulae to do your calcs using this. http://irowiki.org/wiki/ASPD
