What are monster's weaknesses in the dungeon?

I have come to you Sal's place for OSRS GP advice on Dungeoneering. Yes, I'm the one who requires help this time. I've often wondered how to determine the right threshold for praying for monsters. That is, at what point for each type of monster should I pray prayers for protection and offensive prayer? By type, I refer to shades, warriors, rangers, magers, bats, skeletons and zombies as well as demons, rats, brutes, pickaxes and so on.

If a monster is a level 2 then you shouldn't pray for it, and for most rangers who are above tier 7 , you need to pray. most likely, mages, and melee warriors can be brutally hit after they've gotten katagon, so yes, pickaxes do hit like hell . So yes that's a fact. But brutes... meh.

This isn't directly tied to Dungeoneering but it is connected to it in some way. Is 1.2M enough to take me from the 52 RC level to the 70 RC, or do I need more? Making nature runes can be the best way to make profit(iirc) So, yes this is enough. If I use an SSH do I remove off the hood every time that I enter a room that has hoods? Don't take it off since it still protects you from the hood safe monsters, always pile the mage.

What are monster's weaknesses in the dungeon? Please provide as much detail as possible. Crush on zombies, skulls - slash, melee warriors wearing plates crushing and melee warriors with chains - stab rangers/magers - cut.

I'm not sure which armour is best for my particular level. All suggestions are welcome. Thanks in advance. Because you have summoning Ill assume you're a part of the group. This is all dependent on what you're doing and how you building your strength? I'll assume you are using Slayer because it's a excellent training, if that's the case , then get a Black Mask/Slayer Helmet, Bandos Chestplate/Fighter Torso and Bandos Tassets. If you're unable to afford the tassets then of course just purchase normal platelegs.

For boots get some Dragon Boots, gloves buy old school rs gold try to find Barrows Glvoes or if you cannot find them, try a combat bracelet. The amulet has two chocolates, a fury if you have the money or glory if you're strapped on money. If you are looking for a cape, there are numerous options, so select the finest you can. If you're training to be strong, the one thing to have is a dragon defender . that's what you want!
