[quote]Has anyone ran Presage, when you get to the last encounter and to turn on the switches to set up damage. The boiler room switch, like the burn ticks more damage?! I found this problem when the Portal happened. The usual way I survived that was Warlock dive, healing naid or having the Brawn on but still. They either make turning on the switches faster or decrease the burn damage.[/quote] Try going in with your Praxic blade , other sword or Glaive ( like Vexcaliber which gives you a void overshield ) blocking WHILE turning off the mid boiler switch ( I always save the mid room for last so it drops immediately back to normal temp )
