I've cleared about 50% of Madurai tree (the 50% that matters, meaning maxing the triggered passives and cooldown bonus), which is the straight up durmag tree. Overall, it makes all my stuff deal 1.9 times more damage (the extra damage divided between the three Physical damage types, which adds them to weapons that normally don't deal physical damage too). But honestly, the much cooler thing is that the Slashing part of the triggered passives also makes almost every weapon capable of on-death gibbing. It's just so awesome with something like Soma Prime to watch things get blasted to shreds.
Speaking of gibs, that's also the best part about the Azima, since it's capable of gibbing. Besides that, it's a decent machine pistol, having a fast reload, big magazine, low recoil, high accuracy and rate of fire, and decent damage and ammo capacity. However, the secondary where you fire the magazine like a Tiberian Sun discus grenade is really underwhelming.
What it does is fire the magazine and all the remaining ammo on it, and once it has bounced once off the ground and landed (this seriously takes too long), it pops up and starts emptying the magazine in a 360 degree spread. Now this is a bit of a problem because IT HITS ANYTHING THREE TIMES AT BEST before running out with max ammo. So you spend 75 ammo to get three hits per target (the range is small too). If it actually had some kind of strong close rand shredder capacity it might be worth using (since it needs to achieve at least reliable 30% of magazine worth of damage per target to be worthwhile in most situations) that doesn't behave like a clip spraying its contents all over the place but a real fucking grenade alternate fire. But no, it doesn't behave like that, and is probably the worst secondary fire function in the game. The only way it could be worse if it shot out Sheevs.
