[[File:Paragon-utility-p2.JPG|thumb|300px|Life on Hit via Paragon Points.]]LoH or Life on Hit (or Life per Hit) is an item affix that does exactly what it sounds like; delivers X amount of life per successful hit on returns health to the character each time he/she uses a skill with an animation, and hits at least one valid target. This affix is found in random affix slots on weapons, rings, and amulets, and Players can also be found in inherent bonuses add Life on numerous Hit via [[legendaryprimary affixes]] and [[set items]] of all on many item types. LoH is one of the most popular , and valuable modifiers Life on Hit can also be added with Paragon Points spent in the game, and most players seek to stack up a large amount of itUtility Tab.

This modifier is called "LoH was much weaker than [[Life per Hit" Steal]] in D3v, but with Life Steal removed from the game in Reaper of Souls and while it works in the same way, it takes on LoH became a much more important role due stat, and most players find it essential to the removal stack a fair amount of Life Stealit to remain alive during combat.

==Patch 2.1 Changes== Prior to [[Patch 2.1]] this [[affix]] worked more or less as it seemed, with X amount of life returned for each hit on a monster (though the proc chances for each skill affected it). This function made LoH very powerful when hitting multiple enemies at one with AoE skills, and much less useful against a few or a single target.  Life on Hit was revamped in function in the [[Patch 2.1]]. Blizzard's official explanation:[http://diablo.incgamers.com/blog/comments/blizzard-explains-the-big-life-on-hit-changes] <blue>Life on Hit has undergone a number of changes, and it can be little confusing at first. I’ll go over how LoH is currently working on the PTR, but it’s also good to keep in mind that it’s still subject to tuning. The bullet-point basics:* You gain your Life on Hit amount per cast, so long as you’re doing damage.* The amount healed per cast does not change based on the number of targets hit.* You continuously gain a portion of your Life on Hit value while channeling.* We’re increasing LoH on items by another 100%, and LoH in Paragon by 50% in an upcoming PTR build* We’re aware that this needs tuning, particularly with large packs of monsters, or those with Reflect Damage. More long-form explanation: Currently in the live game, you’ll receive Life On Hit when an ability hits an enemy, and then that mechanic is run through the proc coefficient of the ability itself. As a general rule, this means that many AoE skills give very small amounts of Life On Hit vs. single targets, and you typically get large amounts of Life Steal==on Hit against multiple targets. We want players to be able to heal consistently at the times you need it most: Boss fights and Elite fights. To support this, we’re altering some of the conditions of Life On Hit. Life On Hit will now trigger once per ability activation as long as that ability requires an animation*. This means casting Magic Missile, Frozen Orb, and Blizzard all provide the same Life On Hit per cast. Channeled spells provide an equivalent amount of healing over any given period of time to non-channeled spells. Not only does this allow you to gain more Life when you’re attacking a low number of targets with AoE skills, it provides more consistent healing between various skills, and it also separates Life On Hit from the proc system. This last benefit is important as it means we can be more generous with allowing Legendary items to proc various effects. All of that said, there is still some tuning to do now that we’ve adjusted how Life on Hit works. We’ll be keeping an eye a close eye on it, and continue to make the necessary adjustments to get it in line with where we want. *Attacks that deal damage, but don’t animate (like Overpower, or Frost Nova) do not trigger Life on Hit. The intention is to prevent double LoH procs per animation cycle since these skills can be cast while attacking, or channeling. </blue> 

Life Steal heals with a percentage of the total damage done, and therefore scales up considerably for characters with very high damage. ==Life on Hit always delivers X amount with a successful hit, and is not subject to percentage decreases on higher difficulty levels (as Life Steal is), but LoH does not [[proc]] with a number of indirect skill effects, while vs. Life Steal often does. ==

For instance, the Monk's [[Sweeping WindLife Steal]] was a much more powerful affix in D3v. After [[Loot 2.0]] skill effect procs with Life Steal but does not was removed from the affix pool, and legacy items with Life LS are non-functional on Hit, making Life Steal a far more valuable modifier for characters using that skilllevel 70 character.
