The slayer causes 200% to 300% damage to specify monster. As a result, slayer is more useful than Artifact, I suggest to add a scroll (loot from monster or purchase from shop) to add the slayer to weapon. Further, it need to kills 100 of the monitors to make it effective.
Lord Calcion is very time-consuming, I suggest to reduce the items from 80 to 40.
For the spider greater cave, I suggest to set it to 3 levels, silver > gold > diamond key.
For the Lizzogoth map system, it is arduous to go to level 4. Suggest to accumulate the maps instead of collect all 4 piece.
For the darkling camp, it is difficult, more difficult than the dungeons. I suggest to slow down the respawn rate.
I agree with you. I had killed hundred of Lizzogoth and heretofore. Unfortunately, I had never a chance to got to level 4 maps.
To be candid, I think that it is too hard to go to the level 4. I will suggest to use accumulated system to go to next level. (I think someone had suggested but I forgot ...) Let's say 10 maps (no matter 1, 2, 3 or 4) can be combined.
I will suggest there is a tool which can be purchased from Shop to upgrade the gem.
-The tool can be used for 100 times
-It can combine lower grade gems to a higher grade. e.g. 3 to 1
-Meanwhile, we can financially support the server.
