I dont see topic with Pyro builds so make this one

SPECIAL:
5 STR - Flamethrower Fuel have high weight so 5 is minimum to not being frustrated when cant load more ammo

9 PER - For better orientation on the battleground.
10 END - obv
1 CHR - obv
4 INT - For players who dont want bother requirements of certain merchants or dont have plenty of time to grind levels.
10 AGI- For two bursts in short time.
1 LK - For fun

If you choose to set INT at 1, i recommend spend that 3 points in luck. Always its a lower chance to explode Incinerator in your hands

Some tips:
- position yourself in the way that burst hit multiple enemies at one time.
- if you want hit only one crit/npc/char, shot when crit/npc/char are at maximum range of Incinerator( of course check there arent other crit/npc/char on the way)
- always burst in opposition to your allies, becouse even if you shot at crit/npc you can hit or even kill, when at low hp, your allies by accident.
I play this build in PvE and its pretty funny
