Math Help: Magic Weapon with Deadly d10 and crit

[Freder1ck]

So, a short bow with deadly d10 does:
1d6 + Str

Then, on a crit it does

1d6 + str + 1d10 + str

Then as a magic weapon:

2d6 + str

Then, as a magic weapon and on a crit:

4d6 + str*2 + 1d10

Ok, let’s break this down. Criticals double your weapon dice, including extra dice from magic weapons. Deadly adds a die or more on a critical based on quality of a weapon.
A normal Shortbow doesn’t add str, a propulsive adds half str mod.

Mundane Normal or expert Shortbow. D6 damage, deadly d10.
