How to use the PvP Helper and not get banned

Quoting from The Grand Archives Discord Server:

What DOESN'T ban you?: All things that don't remain in your save is safe: params, current health value, current MP value, etc. Some stuff that remains in your save: ItemGib for all normally obtainable items (even key items), GiveRunes, ClearCount (NG cycle), Gestures, Last Grace, Bonfire Warp, flag activation/deactivation and changing (removing/adding) invasion zones for Near/Far invasions. Cut content gestures and gestures that can be conflicting (such as The Ring Pre-Order gesture without pre-order).

What DOES ban you?: Editing attributes to nonsensical values, i.e. if your level doesn't match your stats, or your stats don't fit your class's stats. You can change your initial class as long as the end result makes sense. Editing your name to have more than 16 characters. Equipping or using cut content.

What is unknown?: Modifying GameData.

Specific to the PvP Helper

ItemGib There may be a case where either Cut Content or things that shouldn't be able to be given may appear in the ItemGib. As long as you don't go online with those items you will be safe.

ChrType Changing your ChrType to anything but normal then going online will 100% get you banned. As long as you change back to normal before saving your save file, you will be safe.

Conclusion

If it feels too suspicious, then its probably best not to do it. But for 100% safety, do not use the helper online.
