TFT Set 13 Roll Odds & Leveling Economy: When to Roll vs Fast 8
Understanding champion pool bag sizes and shop roll probabilities is the foundation of competitive Teamfight Tactics. Whether piloting a 1-cost reroll comp or pushing Fast 8 for high-impact 4-cost carries, mathematical discipline dictates your lobby finish.
Slow Roll vs Full Roll Down
Slow rolling above 50 gold earns max interest while naturally hitting upgrades. If your lobby health falls below 40 HP, transition immediately into a full roll-down to stabilize before you risk elimination.
Bag Contestation Dynamics
Because champion pools are shared across all 8 players in the game lobby, opponents buying unrelated units of the same cost tier actually increases your chance of seeing your desired champion.
Key Strategic Takeaways
- Set 13 Bag Sizes: 1-cost (30 copies), 2-cost (25 copies), 3-cost (18 copies), 4-cost (10 copies), 5-cost (9 copies).
- Optimal Reroll Levels: Slow-roll 1-costs at Level 4/5 (55%/45% odds), 2-costs at Level 6 (40% odds), and 3-costs at Level 7 (35% odds).
- Fast 8 Timing: Level up to 8 at Stage 4-2 or 4-5 with 30-40 gold to capitalize on 18% 4-cost odds and 3% legendary odds before the champion bag empties.
- Geometric Probability: If two opponents are already running your 4-cost carry (taking 6 of the 10 copies in the bag), your chance to hit drops by more than 60%.
