I took Triton the health/armor route all the way. I figured I use him more as a supplement hero to my healers, heal overtimes, etc. I need him alive. His attack is a bonus, but the main specialty of him is his 39% heal increase as it works with elemental links, basic heals, damage % heals, Heal over time. The mana boost to me wouldn’t be noticeable considering my highest mana troop is lvl 5 atm. I preferred the bonus armor, and you also get that bonus attack and bonus attack again next nod. If you go the armor/heath route all the way, you will pick up some attack in parts which is nice too.
