lol take alot of sara pots if your tanking if not you could survive a 3 man group my hp is like 93 and range 82 and mage 87 but the 99 str is da same as me so you could survive we both have 75 def =p
And to OP, yes you could, but ide get a gs since it's nearly impossible to find a team since most of them rely on crashing worlds (since they're so crowded), so they require the best item possible. Actually, most teams require 130+ cb and ags, but if you're lucky you might be able to find a noobish team to join thatd let you use a whip.
For bandos, you generally need 85+ attack and str, or 90+ ranged.
I solo'd it with 60 def... bandos isn't hard compared to the other gwd.
If you have 90+ ranged or 85+ atk and str, you could manage 1 kill. Thing is to kill it fast since the minions hit you quite hard.
Lots of people go with just 70 def... but their melee offensive stats make up for it. Bandos is one place you see a lot of lvl100 barrow pures and such, unlike the other gwd.
