I'm somewhat new to the game, and I'm currently leveling an acid-built summoner. I'm really liking it so far, but I have a few questions on rubies.
-Are the Desecration rubies 100% necessary? I currently have r1 Desecration, to get to the Master Summoner rubies, but I'm debating on whether or not to get the other two. As of yet, at level 20, I have yet to be below full mana after killing something, thanks to the two Blood Tap rubies; does this mana regen become less sufficient at higher levels?
-Is Accelerated Metabolism at all worth getting, or is the damage pretty negligible? These rubies are the reason why I'm debating on the Desecration rubies, since I can grab either of them on the way to Concentrated Acid.
-How good is Howl of Death? Is it really only worthwhile for PvP, or is it useful for PvE as well? I know that acid builds aren't as effective for PvP, so I'm planning more for PvE.
For reference, my current build is going to look something like this. I just wanted to ask about a few rubies, since I like to plan ahead and still have time to switch a few around.
I have Hellion simply for solo leveling purposes, and may respec out of it at higher levels if acid summoners are easy enough to solo grind with without one.
