Man, I am getting slaughtered due to the -20% elemental defense on Cruel. How do people even play on Merciless with the -60%??? There's just no way to get your resistances up high enough.
Take a few passives for resists, theres a few very good ones in the tree
I also take the 8 resist from bandits on normal , it helps so much while leveling and they'll add bandit respec in a while anyhow
You should also always have 3-4 extra rings in your inventory , I always carry some rings with high resists of each kind just for those few bosses/special mobs that require capped resists.
On another topic:
Man scion with spectral throw is OP as hell
I got from act 1 normal to act 1 (nearly at merveil) merciless in about 8 hours
Just been running through every map ignoring enemies , joining groups so i can have a teleport up to the boss/objective
Went to fetid pool and the flooded depths while I was 10 levels below the map level and still crushed everything due to sheer damage and lifesteal (and the insane amount of armor you get from the passive tree)
Only died once (in flooded depths) and that was because I forgot to swap my rings and went in with -5 frost resist and died while frozen
My archer was always 2-4 levels overleveled and could not man tank AT ALL in act1 merciless (despite 2800 hp)
A good build and 4 link gear and the right flasks makes a huge, huge, huuuge difference
Didn't take blood magic, using hatred aura for the frost dmg bonus, not one mana node or regen node leaves me with 70 mana
my curse (warlord's mark) costs 45 mana (I need a cast on damage taken gem)
using spectral throw + life on hit + LMP + faster attacks which puts it at 25 mana cost (for single target I use double strike with life and mana leech and melee physical dmg)
So I get < 3 casts before I burn through my mana pool but because of:
-warlords' mark curse granting 4 percent mana leech
-both my life flasks having craving suffix (2 percent of dmg leeched as mana)
-a ring with 1 percent mana leech
I never go oom and can make do with only one mana potion
It's so nice to be able to use two quicksilver flasks, combined with the warlord's curse refilling flasks (and some good 25 percent speed boots) I get to run at insane speed 90 percent of the time.
Life on hit + spectral throw + very high attack speed from build means I can use the life flasks just for the mana leech passive (and emergencies)
Pretty happy with this synergy
Now I just need a cast on dmg taken so I can use Enduring Cry, Immortal Call and Molten Shell
