I've been thinking awile back in doing this. This is a guide for the fight cave minigame
Gear for magers:
Virtus mask
Virtus robe legs
Battle-mage robe
Polypore staff
Arcane stream necklace
Goliath gloves (white)
Ragefire boots
Arcane spirit shield
Completionist cape or max cape (since comp cape requires fight caves to be completed before you can wear it)
Seer's ring (i) for donators, for non donators use the normal seer's ring
(Igonore the aura it doesnt give any bonus)
Gear For meleers:
Torva full helm
Torva platebody
Torva platelegs
Chaotic maul
Comp cape/max cape
Amulet of fury (if your looking for defence bonus) or amulet of strenght (wich will give you a better crush attack bonus)
Steadfast boots
Goliath gloves (white)
Berserker ring (i)/normal
Gear for rangers:
I´ve seen people using pernix has ranger gear but what we are looking for is a good crush magic or range attack bonus and i've seen that vanguar set gives 253+ range bonus (in attack bonus) than pernix wich only gives 252 so here's the rangers gear:
Vanguard helm
Vanguard body
Vanguard legs
Chaotic crossbow
Chaotic kiteshield
Goliath gloves (white)
Archers ring (i) or normal
Comp cape/max cape
Glaiven boots
Amulet of ranging
Dragon bolts (e)
Note that it might give lower than 253+ range bonus due to the cape and the ring
This are the best gears for fight cave unless you find a better gear please let me knowand this are the iventories for each gear
Magic inventory:
6 prayer renewal flask (6)
5 Extreme magic flask (6)
12 rocktails (incase something goes wrong and you get hit by the meelers and the magers)
death water astral blood and earth runes for ice blitz to freeze them and for ice barrage for hiting various opponents at the same time
Melee inventory:
Even in melee gear i recommend to use the ice blitz since the magers hit high in both magic and melee and its hard to defend against melee and magic since you can know when he is gonna magic but not when he is gonna melee so i recomend ice blitz for the magers part
6 Prayer renewal flask (6)
3 Overload flasks (6)
3 saradoming brew flasks (6)
11 rocktails
Range inventory:
7 Prayer renewal flask (6)
8 Extreme ranging flask (6)
13 rocktails
To get the 3 gears without having to search for the ids and spawn simply do ::fcgear it will give you the 3 gears (runes pots and food not included due to leak of space)::fcgear has been disabled the items will be added to a shop soon
