Hello ,Im a 180+ rogue on android server whose focus is shifted to pure bossin(will level after tower update)
We haven't taken down hrung/mord yet so gear is a lil sub par compared to iOS
Had a few doubts regarding build and gear and I hope the top rogues will help on this
1)Most bosses now have high defense and resists so i thought it would be much more efficient to stack up damage of different kinds, rather than just fill str cause it's just pierce dmg, like cold/heat/poison dmg
I want to know if autos are more effective against these bosses rather than spamming skills like ss sneaky qs etc
2)I currently use dl gloves and breeches, 90 cold dmg helm, obsidian bp/boots for added poison dmg,Event str ammy, dex brace,, evasion ring., 50 str vit riftskull, 60 cold dmg dragon charm. And lastly if it's best to go for 45 dmg aggy ringsx2 or a royal +grand ss for bossing? That I am a bit confused atm
3)I always put the team over myself so went support dps, maxed ss qs poison weapon (buffs archers), dble attack and expose weakness 1000+ reduction
285 str 335 dex 5.2k hp, 1500ish autos.
Any changes to stats gear skillset will be much appreciated. Thanks

If u want to go support I would drop a skill for smoke bomb as well (probably double should be dropped)

Dmg rings better then ss rings, ss gets avoided 90% of the time unless you have high cunning. Also I would lvl just a few times more if you can especially if your goal is to kill mordy and hrung, and 180-185 is generally easy mord cave, after that point its a grind though. If your a support rogue i would drop posion weapons and use smoke bomb, smoke bomb decreases the bosses defence which means everyone has a higher chance of their autos landing, very beneficial.

I see,thanks a lot.I didnt max,smoke because another rogue in clan,maxed it.So aggy 45 fire/cold,is better than,ss.I had a feeling and ran some,tests,on mobs but thot ss is poison I am adding poison dmg.So autos are more beneficial at this point huh .
Also i wud love to add some more poison dmg gear. Atm using bounty dagger, poison skill and obsidian bp/boots. Any recommendations on gear. Thanks again
