The items you are talking about are looted by each warzone boss, they are:
- Warzone 1: Deathstrike's Snippet
- Warzone 2: Gnomevil's Hat
- Warzone 3: Abyssador's Lash
When you deliver these items to the NPC Gnomission, you won't need a Red Teleported Crystal anymore, to enter that specific Warzone.
For an example, when delivering Deathstrike's Snipper, you won't need a crystal to enter Warzone 1 anymore.
You can only deliver items for the Warzones which you have access (but you don't need to have it completed yet).
- Warzone 4: 15 points or 10 if you already completed WZ 1,2,3 at least once in that character
- Warzone 5: 15 points or 10 if you already completed WZ 1,2,3 at least once in that character
- Warzone 6: 15 points or 10 if you already completed WZ 1,2,3 at least once in that character
To gain points you can:
- Complete the daily tasks from the NPCs: GNOMUS / KLOM STONECUTTER / LARDOC BASHSMITE
- Deliver Suspicious Devices, each grants you 1 point
PS: Note that there is a level 100 requirement to enter Warzone 4,5,6 area :)
