Ninja Tricks and Chemist Bombs

[Viladin]

So a player brought to my attention a combo that his character might be capable of and I was wondering if it was supported by the Rules.

it involves the Ninja Tricks, Double Toss and Palm Throw, and Chemist Bombs.

Essentially Throwing 4 Bombs with 2 attack Rolls.

Character in question is a 3rd level Freelancer. Im thinking it doesn't work, but if it does that's 8d6 bomb damage

Double Toss and Palm Throw does not work with Chemist Bombs. They are a Supernatural ability, not a throwing item.
