*DARK GIFTS*
From what i see of this arena the object to manipulate are actualy inexistant.

*DEMONIC GIFTS*

Force Projectile, being a ranged attack it would most likely be very hard to hit Sonic with them.

*GLYPHS*

They are allmost all ranged attack so it would be most likely very hard to hit Sonic with them.

Raziel Glyph attack wouldnt last forever it would only help him stay in the game a little longer. He will end up draining all his reserve !

Also Raziel wouldnt always get away in the Spectral realm without being hit. Sonic could use his Sonic Wind attack to damage + stun for a short period. It would give Sonic the time to get in range for a Hyper Slide or/and some other attacks.

It will no always be Raziel waiting for Sonic. Sonic can just stand still and wait up. Then once Raziel start getting closer he can start getting speed and be ready to strike !

Cracks never actualy slowed down Sonic at his speed he just ignore them or if some are big enought he could jump over them and continue running(this would hardly slow him down if it even slow him down).
