M: AT #3 - Flame Princess/Prince & Glasses of Nerdicon & Instant Bath Serum

[UncleBob]

Glasses of Nerdicon double One Shot items.
Instant Bath Serum is a One Shot, flame attack that gives a +2.
Flame Princesses/Prince gives a +1 to items that are already flame attack items.

So, is this (+2+1)*2=6 or (+2*2)+1=5?

So Math!

*edit* - I forgot, Princess Bubblegum gets a +1 on all One Shots that give a combat bonus... so, same as above - is this +1 doubled if she is wearing the Glasses of Nerdicon?
