For Rimeheart to proc, you need to hit frozen enemies - which is not a big problem with Wizard due to Frost Nova/Halo of Arlyse or other skills. I can see a setup using Ice Blades for more chance to freeze people, maybe adding an Iceblik gem to make the blades chill everyone automatically.
However, there are some fundamental flaws on this (and it's not Iceblink though it's a big hit on damage).
First of all DMO doesn't buff all character damage but only some specific skill damage. So while with an Ice Blades setup you could potentially deal quite some damage, Rimeheart damage isn't actually buffed. Basically, it's not another Manald Heal until you use Tal Rasha (the set buffs all damage including Manald Heal, that's the reason why TR/Archon/MH was strong in S9 and why it is in S10 with Hydras).
Second, Rimeheart procs on freezed targets - which is bad, because of diminishing returns on CC which hits the uptime of freeze pretty hard. While you can theoretically spam freeze around you, the actual time the targets are freezed is much lower, thus hitting hard the Rimeheart proc. MH is so strong because it procs from a passive and doesn't matter of the stun connects or not, the damage will still be triggered ignoring the CC diminishing return.
TL;DR: DMO with Rimeheart may work, but the performance won't be good, mostly because Rimeheart is a bad proc mechanic compared to a similar item (Manald Heal)
Hi, i was actually searching for rimeheart info and got to this post. You explained very clear the proc mechanics but there are some things left in the air that i can't actually find anywhere else. Since you know a lot about damage mechanics i would be grateful if you could help me with this:
Since you have asked specific question, i'll answer point per point.
- Rimeheart damage should be increased by LoN. It's a flat overall dmg increase like TalRasja so i don't see why Rimeheart shouldn't be affected.
- Needs testing to be sure. MH doesn't proc AD, so i'm inclined to think that RH won't proc it either. Anyway i don't recall anyone trying that so it's just a guess.
- Sure. CHC/CHD affect all procs like normal blows (only exception i recall is the Impale bonus of shadow set that is not affected by Impale runes for balance reasons).
However. Still RH procs on freezes, so the only actual two skills contributing to procs are Vengeance and Rain in that build. Cold grenades only chill enemies so have literally zero effect - that's the reason why Frostburn are mandatory. Honestly, it's worth trying imho but i'll just dutch rain and aim to 100% uptime of Vengeance (which you should have anyway). Also Calamity is a pretty bad weapon, fortress Ballista is what you want to use for great toughness boost. I'll also suggest to use a follower with the freeze dagger so it's a guaranteed freeze when the monsters have less than 20% hp (but again, only the first hit if they're not being frozen again).
The problem remains in freeze uptime. While DR should be substantially less due to less spamming of freezing abilities, it's just not enough to have consistent procs. Freeze DR hist pretty fast reducing the uptime by a lot, meaning you will have less chances to proc stuff.
Another thing: from wudijo theorycrafting about the grenade belt, apparently the cold rune doesn't get the full dmg increase from hit, so it's basically suboptimal to use hit. Could have been a bug and it's been fixed, but again, no one has tested it.
All-in-all, it's worth trying it imho. Worst case scenario you get stuck at a low GR due to lack of damage/toughness/whatever, and nothing of value is lost. In anything, you have tried a new playstyle that has the chance of being entertaining and viable if everything works as expected.
Tbh, i think i'll fiddle a little on d3planner. Anyway my biggest gripe is RH proc which isn't as reliable as MH, and should be the big source of damage.
