IG-88, like R2-D2, is one of those characters that takes longer to level up than the normal character, like Anzat, Shistavanen, Han Solo, C-3PO or Sakiyan, but not as long as others, like Spider or Terentatek. In addition, if you use the straight flush method for each training cycle, then you will only need Training Items 5-4-3-2 at Level 34 to max out to Level 35. Unfortunately, replacing Training Item 4 with Training Item 1 and an additional 2 are not enough (see screenshot below), so you will have to spend the extra 6 Energy to either get Training Item 4 or you will have to do another training cycle and use more credits. The decision is yours -- use Energy or use Credits, both of which are valuable commodities in this game.
This is a list of the total credits required for the entire leveling-up training process within each tier. The assumption is that you are using the most optimal combination of Training Items.
- Tier 2: 100 credits
- Tier 3: 1,325 credits
- Tier 4: 13,525 credits
- Tier 5: 58,400 credits
