| How to Beat The Sinner |
|---|
Players must be ready to face The Sinner in close combat range. The boss can move quick and it may be challenging to dodge all of its attacks. It is recommended to attack frequently while it is idle or charging attacks.
The main character in this section can activate slow from the Perfect Dodge ability. To land more hits, players can use this tactic to get more damage in.
Another thing players have to watch out for is that this boss can also teleport in the enclosed space. Wait for The Sinner to reappear and then move away to reposition the main character for an attack against this boss.
| The Sinner has a quick sword attack that may be difficult to dodge. The boss will move up close to the player to land an attack. |
|
| How to Dodge | In close combat this may be tough to avoid, but players can observe the direction The Sinner is facing and time their dodges. |
|---|---|
| The boss uses the same sword charged attack as the main character. There is a brief casting period before the boss launches its attack. |
|
| How to Dodge | When the boss is charging its attack, players can use the dodge move to quickly step away from The Sinner. |
