How i can have life leech before clister with doryans passive?

Search for some Enchanted boots with "Damage Leeched as Life" on them.
Random pairs are pretty cheap. I grabbed a remotely decent pair for 15c.

Use these with Soul Tether belt and it's pretty gg.

Arcanist brand - volatile death - cascade


Storm Secret Topaz Ring:

cwdt lvl1 - cascade - desecrate - gmp - volley - lmp - unearth // Undertaker 12corpse per corpse skill

Brand recall 166.6%cdr
General's Cry


Blow up 45corpse with your instacast brand recall, every 1.5sec

fire leech amulet is ok

you no need life leech in this game!

The Agnostic: when life is not full, loose 20%mana per sec to gain that match health
*
2 (if have 100%more mana then health)
*
2 (if have 50%MoM)
=
80% life regen per sec

damage taken gained as mana buffed, with +13%for free since last patch
10%spirited responce jewel+10%passive+10%boots+10%helmet+8%ring+8%ring+10%watcher jewel = upto 66%
add some increased mana recover jewels, if want more

Can also increased MoM
