Better ability bar would be:
Berserk on 2nd and 4th phases
Activate freedom when running to an artifact, and anticipation when running back. This adds an extra 16% adrenaline, and 10% damage reduction from anticipation.
Debilitate is a useful melee ability if you don't have high end melee gear
Should bring Armadyl battlestaff (air surge) & mage top/bottom as a gear swap if she does hardened carapace, even if you have drygores. It speeds up kills in the long run.
Always stand 1 square west of the first artifact, due to there always being a gap in the firewall there.
Its a more advance technique that takes practice but:
You can completely avoid firewalls without using the gaps, like woox16 does:
The way it works:
Firewalls move at 1 square/tick if checks for the player twice each tick (meaning it hits you twice if you stand still).
You character runs at 2 squares/tick, so with proper timing you run through the wall before it actually detects you and you don't get hit at all; if you mess up the timing you get hit once.
I'd take bandos boots and gloves over torva or pneumatic for the sake of extra damage, but they don't degrade and are much cheaper
