How to Beat Si Boss
Remember Si's Painted Attack Zones
Si's Boss Fight includes several attack patterns. When she unfurls her scroll, she will paint specific areas on the scroll that will act as attack zones.
Learn the patterns, then try dodging them to avoid taking damage and getting knocked back.
Attack Zones Will Change in Black and White
Si can also change the entire landscape to black and white. When she unfurls her scroll for a second time and changes the arena's colors, the attack zone patterns will be the inverse of the original pattern.
During this phase, you should stay within the painted areas because she will launch an attack in the unpainted areas.
Stay Away From Ink Pools
The Si boss can make Ink Pools during the battle that can launch an attack after a short period. Try to stay away from these zones to avoid taking damage.
Her Giant Ink Lung can also create a large Ink Pool that surrounds the entire battlefield and deals damage over time if you stay within its range. You should run to the center where the pool cannot reach you before it explodes.
Watch Out For the Summoned Spirits
The Si boss calls out different spirits to attack your team. These spirits cannot be targeted, as their purpose is to perform a powerful attack. Learn each spirit's attack pattern to avoid taking damage.
