Well due to the recent update the max for Barrage went from 30 to 33 while using a +10% magic strength bonus weapon like Master Wand.

 

 

 

I will try to get the maxes for other spells later and I'll try to get the maxes for the Miasmic spells as well

Every combat spell excluding magic dart, Iban Blast, Saradomin Strike and Flames of Zamorak can get the extra 10% bonus the new maxes are simply original max times 1.1. Since those spells require a staff which doesn't give 10%

 

The only question really is are they rounded up or down.

Thanks, this has been fixed up.
