I've carried on playing my Minotaur based 2Bard/8Ftr/50RDD toon and he's up to 52 now and I'll say that they're very durable and put out a decent amount of damage, rather than using all my stats on Str I've used a few on Con to get 22 Con and the Epic Damage Reduction feats. With the right equipment and buffs an ideal up-front toon for Beholder and Dustbone runs. Add to this Pyramid and Hell runs.
What is good HP for this build at level 30? Right now I have exactly 600 HP without the equipment. With equipment I have 780 HP and im not sure if this is good or not. If you want to chat with me on game about this my Character Name is -TheFallenDragon-. Thanks.
Depending on the final Con you have (and you really need to max this before LL as hps gained are not retrospective in LL) you should end up with about 1300-1500hp at level 60. I think my RDDs have 1498 and 1472 hps but I had a decent Con on both of them.
You'll have as much as you've bothered to spend points on (and RDD bonus con) FYI I ended up with 22 and 24 on my builds, any value near this should give you a goodly quantity of HPs and the ability to take EDR and yes I would recommend taking this if you can as you're not a DD.
Get the Scythe! What's the point being huge and able to use a two handed weapon and shield and having a colossal critical potential if you don't use a scythe? IMO anyway Both my RDD scythe wielders do huge criticals and its fun to see you mash things in a minimum of hits. You won't get the improved sr until you've either died or the server has been reset.
