1.3 getting you down? Let me fix that for you.
How to Get Lots of Temp Health
This is some help for those who are struggling with no THP gain on ranged kills. It's a work-around, so to speak.
If my squishy bot team beat Legend with 3 bosses, using these builds, then this will probably work for you.
Take the talent that gives you 50 THP on ult. Now, use Boon of Shallya. Now, take the talent that increases all healing by 30%. Enjoy 85 THP, whenever you ult. That's almost a full heal.
Take the talent that gives you 50 THP on ult. Use Boon of Shallya. Now you are getting 67 THP whenever you ult. That's a bit more than half of your health. You have some regen as well.
Again, you could take the talent that gives you 50 THP on ult. Mix it up with Boon, and you're getting 67 THP whenever you ult. Could you use your green hp to vent and run 100% on THP gains? Might work in theory.
Take 30% increased healing. Then put on Boon. Get a support character, like WHC and Merc to heal you. That's 40 THP every 49 seconds from Merc. Potentially 5 THP from every elite/special kill from WHC.
20 THP over 5 seconds with your ult. Take Boon, and it's 26 THP. Not a lot to work with, but it's something. You might want a WHC to be giving you 4 THP every time an elite/special dies. Huntsman is pretty good at killing elites, quickly.
Well, you've got the short straw. Merc Kruber is your friend.
If You Play with Bots
With Boon of shallya on your bots (or yourself) his heal will give you about 33 THP every 49 seconds (max CDR). It adds up fast.
Witch Hunter Captain:
He has a talent that grants 3 THP (maybe 4 with Boon) for every elite/special that is killed. It goes to the entire team. Elites are quite common on the higher difficulties, so this does end up giving the team a good chunk of extra THP. Every little bit helps.
