Took a while. But for those wondering the patterns:
- First Phase - easy, but keep an eye out for the patterns you can't jump past - they'll be where you'll need to be on the second half of the first phase
- Second Phase - keep more eye on the trails of fire opening and closing. Proper jumping will save you when getting in and out
- Third Phase - Keep your movement to a minimum, and the Fireballs won't be much issue
- Final Phase - Alternate between shots by counting to 3 at every moment. Some imps may be landing sneaky shots, but when one's down, the other shouldn't be too hard due to the damage it takes.
There needs to be more of this, and a giantess on giantess version.
