The shop is the interface in Dota Underlords where heroes may be purchased.
Buying heroes
Each player has their own shop with 5 hero slots. Each hero in the shop is priced accordingly to their tier. Tier One heroes cost 1 gold, Tier Two heroes cost 2 gold, and so on.
The shop can be accessed and purchased from at any time. All units purchased from the shop are rank 1 (
).
Re-rolling
Gold can be used to re-roll the shop. When you re-roll, the shop refills all its slots with new heroes, any hero left in the shop will be replaced. The shop refreshes automatically at the start of each preparation phase and can be refreshed (re-rolled) manually by the player for 2 gold. A free re-roll of the shop is also granted after a combat loss to an opposing player. Free re-rolls do not stack and will be gone if unused.
Blacklisting
Whenever you manually re-roll the shop, any heroes left in the shop from the previous refresh are blacklisted: those heroes are prevented from appearing in any slots of the refreshed shop. This mechanic can be used to increase the odds of seeing desirable heroes, by removing the possibility of getting undesireable heroes.
Automatic refreshes of the shop at the start of each preparation phase may show unpurchased heroes from the previous shop.
Shop odds
The current Player Level determines the odds of finding a certain tier of hero in the shop. Each of the 5 slots in the shop is assigned a hero tier using the tier odds for each Player Level:
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | |
|---|---|---|---|---|---|---|---|---|---|---|
| Tier One | 80% | 70% | 55% | 45% | 35% | 25% | 20% | 18% | 15% | 12% |
| Tier Two | 20% | 30% | 35% | 40% | 40% | 35% | 30% | 24% | 21% | 18% |
| Tier Three | 10% | 15% | 25% | 35% | 40% | 35% | 30% | 28% | ||
| Tier Four | 5% | 10% | 20% | 28% | 32% | |||||
| Tier Five | 3% | 6% | 10% |
The odds of seeing a particular hero in the shop are also determined by the number of copies of that hero remaining in the Heroes Pool, and the number of copies of all other heroes of that same tier in the pool. The choice is random from all the copies of heroes at that tier, with each copy of heroes weighted equally. For example, the chance to get a Disruptor in a Tier Four slot, when there are currently 3 Disruptors owned by players, and all the 12 copies of the other 11 Tier Four heroes are still in the pool, is:
(9 / (11 * 12 + 9)) or 6.4%.
These two sets of odds are applied as follows, independently for each of the 5 slots in the shop:
- Choose a tier for the slot, using the current Player Level and the odds chart above.
- Choose a hero randomly from all the copies of heroes at that tier currently in the Heroes Pool.
Knockout
Knockout mode has different unit odds than Standard and Duos, but is otherwise the same.
| 5 | 6 | 7 | 8 | 9 | 10 | |
|---|---|---|---|---|---|---|
| Tier One | 40% | 35% | 25% | 22% | 22% | 15% |
| Tier Two | 35% | 30% | 30% | 27% | 25% | 21% |
| Tier Three | 25% | 30% | 35% | 35% | 30% | 28% |
| Tier Four | 5% | 10% | 15% | 20% | 30% | |
| Tier Five | 1% | 3% | 6% |
