Non HGH Build Needed
You want a non-HGH and non-squishy build? Damage and squishyness go hand in hand, so I’m guessing that means you want a support/bunker build. My current one is 10/0/30/20/10 : Bomb kit and two utilities of your choice, this build can fit any. I personally like slick shoes stunbreak and rocketboots. Trait healing bombs, larger AoE bombs, HP regen while using a kit, and use Cleric’s gear. You’ll have as much healing and regeneration going on as any guardian on the block.
If you don’t like close ranges, grab Elixir Gun instead of Bomb Kit. It isn’t as trait dependant when you’re using it to support, so it gives significantly more flexibility.
