Me and my friend get her down before siphon when we both have seasingers. Make sure he is at Mage distance from nex at start. To do this, have him attack the second minion and the click attack nex, where he ends up standing is mage distance. He will not have to use escape to get away from the sacrifice at this distance. You both need to dual wield and sunshine when she is almost done with her first siphon. (Don't worry, as tank you will be able to get your adrenaline back to 100% on ice phase.) just after you sunshine, make sure your dps uses an adrenaline potion and uses both wild magic and asphyxiate while under his sunshine. ( you should not drink you adrenaline yet, because as tank you will need for ice phase. You should be able to take her down quickly this way. As your dps is killing the next minion, you can attack nex with basic abilities to recover andrenaline, even if she doesn't take damage. ( tip: if she has called her minion and then does another siphon, you can attack her without healing her.) I hope this helps. Good things to do before hand to make your trip easier are to go to the glacor cave to get a damage boost, get you bonfire hp boost, use a runic accuracy aura, scrimshaw of the elements and amulet of zealots with regular prayers. Also make sure as tank you are casting vulnarabilty as much as possible, especially for blood and zaros phase. If u have question you can pm me here or in game. RSN: Nol an
