Task - Activities Step Limit?

[thepoetwarrior]

Question:

What if I make in "activities" table have 'step' 1 have 20 steps, and 'step' 2 have 20 steps ... all the way to ... 'step' 5 have 20 steps? So only 20 kills at a time can be completed, and once the first 20 bosses are killed, then it'll reveal the next 20 bosses? Looking for a creative way to do this.

Or maybe have 5 different task id's with 20 steps each? Basically 5 different task with 1 reward each that can be combined together as a recipe?

Looking for ideas if anyone has any.

Thanks
