Sirus needs a map marker to make up for final phase design flaws.

He's a pain in the last phase, no clue where he goes when he jets off-screen, and this results in me having about a 50/50 shot of him blowing me up off screen or succeeding.

He takes way too many maps to summon him. It takes about a day and a half of my available playtime to have a shot at a boss who may or may not just screw me over due to horrible design flaws.
