Hi guys, I am new to the tip.it forum but I have been following this topic as a guest for some time now. It has been really helpful in perfecting technique, but if I may I'd like to add a few things. 1. I do believe better mage bonus does significantly inprove efficiency. Right now I burst with +127 mage attack, and I tend to average around 3.4-3.5 casts per crimson, which is a good deal better than the stats of the OP's numbers, which is about 3.7 casts per crimson. 2. Aside from mage bonus, there are two handy pieces of equipment I highly recommend. -A verac's skirt is better to use than proslyte or initiate legs, because you trade off +1 prayer bonus for a MASSIVE defence boost against the ranging dagannoths. I essentially only take hits from the mage walrus and SGS provides adequate healing, no blood spells required. -If you don't have a SGS, take another melee weapon. It saves a lot on casts because you are wasting burst spells to kill the last lobster otherwise. It is cheaper to flip on prayer and melee the last lobster than waste runes bursting it. (This contributes to my better charm rate as well.) Anyway, great guide, very helpful, 2500 more crimsons to 99 summon as of this post :thumbsup:
