I have 83 magic, 81 defence, 88 strength, 88 attack, and 87 HP. Should I use ancients at rock lobsters, or melee waterfiends for crimson charms? I need enough to get me 65-67 summoning.
Waterfiends as it's only for 2 levels.
If it was for a higher Summoning level and you had money to spare then Rock Lobsters for sure.
Rock Lobs are beast charms/magic exp/fast if you have the money.
Good Luck
