I ran so many fire armor scrappers, stalkers, sentinels and brutes on synapes wst thanks to second builds.
3/4 pounding slugfest and 3/3 pulverizing fisticuffs in two melee attacks to stack that energy defense
3/6 eradication (pbaoe) and 3/6 scirocco's to stack that energy resist and defense
now take pool travel powers and stack x5 2 piece Zepher for that ranged/energy defense
overwhelming force in whatever for even more energy defense and knockback protection
i also learned that at level 20, a level 23 SO is stronger than a level 20 generic invention. and that freed up enough slots to 6 slot buildups with gaussians for even more ranged defense. oh and ranged damage sets are terrible for energy/ranged defense slotting
