How to Use the Interactive Map

The Interactive Map both shows the location of key points on the map, and doubles as a collectible checker.

1. Click an icon on the right side to show all the pins of a specific type, or click the magnifying glass button to search for a specific pin by name.
2. Click a pin on the map to see its name and description, and a relevant picture or video if available.
3. From here, click Mark as Acquired to indicate that you've gotten a collectible already. This will change its icon on the map to show that it has been collected, and add 1 to that pin type's Counter.
4. To undo this, click on the same pin and click Restore to unclaimed.
5. To check how many pins you have marked so far, check the Counter in the bottom left, and click the icon that looks like a checklist to see counters for all pin types.
6. If the collected pins start to get in the way, you can hide them all by clicking the green Show Pins button on the left side.

Grigoire Tips and Strategies
Stay Behind Him Use Lightning Resistance Optimize Build and Gear

Stay Behind Him

Girgoire's attacks are mostly to his front, evading through his attacks and repositioning to his rear gives you the advantage of avoiding his attacks.

▼ Jump to Grigoire's Attack Patterns ▼

Use Lightning Resistance

Lightning Resistance potions, gear, and gems can make this fight a breeze since all of Grigoire's attacks are lightning-based.

Optimize Build and Gear

This boss has complicated mechanics similar to Uber Lilith. We recommend optimizing your build and gear to efficiently take on this boss without worrying about DPS and survivability.

Girgoire Attack Patterns

Lightning Platforms and Landing

Square platforms in the area will be hit by lightning. Dodge these by moving to the middle area first, then move outside as Grigoire lands in the arena.

Lightning Balls

Grigoire swipes at the player as his mace releases balls of lightning. Dodge this by standing close to Grigoire and evading through his attack.

Electric Walls

Grigoire summons pillars that connect through lightning. Avoid these walls and reposition yourself as these can drain your health fast.

Knight Summon

Grigoire summons Knight Penitents to his aid. You need to clear these first to have a smooth run against Grigoire, as these knights can disrupt you, throwing off your combos.

Lightning Call

Grigoire calls down bolts of lightning in the arena. Run around and avoid the circles where the bolts would hit.
