Let me know some good build, I prefer anything but sorc and never played druids in HC, is there any build that works fine with not much gear?

No trades, no ladder rws, singleplayer.

Any caster or summoner should be simple

Wanted to try sharpe druids but seems hard, needs a good weapon

Will start with summons necro.

If you wanted a shapeshifter and have no gear, Go with a werebear druid and use shockwave.

Summon nec

druid werewolf is super safe and build is cheap, search budget werewolf youtube.

ripcracker, highlords, 2x raven or 1x raven & leech ring, string of ears, laying of hands, gorerider, duress, jalal, charms for resi and fhr. super cheap honestly and works well on hell.

Single player melee druid wt in my sig!

Holy Freeze Zealot is quite a fun build,also look up a build called towndump werebear druid. Have fun and if you go hc single player,i can only but recommend players 8!
