Base Defense is impossible because there is no multi mode.
You would need to create a new task that would run Base Defense if it could be converted so that it could be done solo.
Add a Lucky box with Mythic Weapon? Rather, simplify cube recipes. Delete recipe "?" and create some instead of him.
1. Cabalist Mythic Weapons.
2. Non Cabalist Mythic Weapons.
3. Non Cabalist Shields.
4. All Unique Weapons.
5. Lucky Skill Expander.
6. Bracelet and Necklace + 5AA.
7. Costumes and Mask is what you get at the beginning of the campaign to kill the boss. Costumes would need to be reworked and removed 90% damage reduction.
It would be much simpler. Half a day of sitting to find the Nemesis Glyph Cage because your chances are one in twenty. And after the cube rework, only three weapons to choose from.
