There are tales from the amazon about a fire mech in the form of a river monster piloted by a fire troll.
The myths say it appears three times per match to melt rear armor only to disappear leaving only smoldering trail.

With very good firing discipline, you can lay down 80 damage in under two seconds from 300 meters without taking internal damage. Full cooling skills required.

Don't bother with any unnecessary cool down nodes. You won't need them.

With the change to micro lasers, I've been fooling around a lot with my Piranhas. After a few different setups, this is the build I've settled on for the PIR-3. I'd call this an off-sniper. Operates much like other single PPC lights, with the down side being no JJ's, but plus being a formidable armament of micro lasers for close quarter combat. Heat is very manageable, and tonnage wise everything fits in nicely.]]> PIR-3 "Nibbles" (4xSPLs, 10x uERS, XL170) Tue, 25 Sep 2018 19:54:15 +0000 https://mechspecs.com/threads/pir-3-nibbles-4xspls-10x-uers-xl170.15022/ https://mechspecs.com/threads/pir-3-nibbles-4xspls-10x-uers-xl170.15022/ invalid@example.com (AngryDre) AngryDre

Very straightforward and self-explanatory. SPLs and ERuLs link up well in terms of duration, cd, and range, and the individual groups run fairly cold.]]> PIR-3 "WubRanha" (10xcuPL, cXL180) Tue, 18 Sep 2018 16:14:49 +0000 https://mechspecs.com/threads/pir-3-wubranha-10xcupl-cxl180.14984/ https://mechspecs.com/threads/pir-3-wubranha-10xcupl-cxl180.14984/ invalid@example.com (CarloArmato) CarloArmato

10xcuPL are now ghostheat-less.

Take a bite and run. Alpha lights need to eat on the go. A little more armor than the PIR-2 version and you can mount 4 lasers in the arms which works nicely with the range of the heavy medium lasers.

Thanks to PGI, this should have no ghost heat. (4 x 8 + 10 x 1.15 = 32 + 11.5 = 43.5 heat per alpha)

Big-ish opener and 10x ERuL to finish things off and carve up other lights well waiting for the Heavies to come off cool down or to bleed off enough heat.

On the one hand I'd love to have the mobility of putting these in an arm and then just dead siding. However, there's just not enough armor to make sure you keep your arm and don't become a stick. The ST points are nice and high though.]]> 2 PIR-3 - "The Chef" (7x cFlamer, 5x cHSL) Tue, 08 May 2018 14:42:26 +0000 https://mechspecs.com/threads/pir-3-the-chef-7x-cflamer-5x-chsl.13705/ https://mechspecs.com/threads/pir-3-the-chef-7x-cflamer-5x-chsl.13705/ invalid@example.com (Purity The Kitty) Purity The Kitty

NEVER alpha strike with this thing: always use 2 groups of 5xcHSL separately to avoid ghost heat.
Simply try to avoid fire and attention, sneak up from behind and deal 65 damage on their backs.]]> PIR-3 "Light Hot Nova Mk II" (12xcERSL, 1xcERuL, XL 180) Sun, 04 Feb 2018 01:11:16 +0000 https://mechspecs.com/threads/pir-3-light-hot-nova-mk-ii-12xcersl-1xcerul-xl-180.13718/ https://mechspecs.com/threads/pir-3-light-hot-nova-mk-ii-12xcersl-1xcerul-xl-180.13718/ invalid@example.com (Remover of Obstacles) Remover of Obstacles

Extra ER Micro Laser because Firepower>Speed>Head Armor.

If you want to shave the head and arms a bit more, you can trade the micro for a flamer.]]> PIR-3 'Chill' (4xcFlamer, 10xcMicroPL, XL180) Wed, 31 Jan 2018 15:39:51 +0000 https://mechspecs.com/threads/pir-3-chill-4xcflamer-10xcmicropl-xl180.13687/ https://mechspecs.com/threads/pir-3-chill-4xcflamer-10xcmicropl-xl180.13687/ invalid@example.com (PyckenZot) PyckenZot
