Combining elements on weapons which already have elements can be confusing.

As Blast is already a combined element it will always be added independed of mods. So the mods you put in combine as if the Penta had no innate element at all. Thus the game adds up all elemental mods with the same element (Wildfire + Hellfire, in your case) and then combines them starting in the upper left corner so Toxin + Fire = Gas and then a sole Cold mod. After that the innate Blast-damage is added to the damage-listing.

If there were mods in it giving Blast (so Fire and Cold before Toxin) that Blast and the innate Blast would stack, however that sole Toxin will never be able to become Gas then.

Best way to max Blast and Gas were to also add the event Gas-mod instead of Cold-damage, if you happen to own it. If not try reload speed or mag size or, if you just want to spam grenades, speedtrigger will give the most dps possible with the penta, but is in most cases not as useful ;) Talking about maxed out dps, i assume the last spot is free for multishot?
