The floor and ceiling move for AddToRoll tables. So if the (say) 2nd last entry still has the same
range so is unchanged.
Imagine a dice is rolled and if the value is 3 or 4 you win. If the game is changed so 1 is
added to the dice roll. You still have the same chance, it’s just that a roll of 2 or 3 gets 1
added making it 3 or 4.
Compare this with just moving the floor. So any roll of 1 is re-rolled, making the range 2 to
6. Your 2 in 6 chance of winning previously is now 2 in 5.
Note that for an AND table all entries below are hit so this does not apply.
In reality the Table entries you want to hit are the last entries since these contain the rare rewards.
There is an example where this is not the case; the Powerful Redono Mount Charm is the 2nd last
entry. The table is AddToRoll and so luck will not change it’s drop chance.
3. Luck works well for AddToRoll Tables
For example the BrimstoneSarcophagi table shown above has a ContainerLootLargeExtra table.
That table is AddToRoll and has a ContainerTrophyArtifacts bucket that contains all the trophy
mats.
The bucket has a range of 99,500 to 100,000 (so 0.5%), but the table is AddToRoll so 40% luck
will make the roll range 4,000 to 104,000 and the entry 99,500 to 104,000. That’s 4.5%
Note the you still need to have hit the ContainerLootLargeExtra table. That has a 75,000+ roll
value, so 25% and then 4.5%
Example Drops
These give some examples of getting a drop. Note that there maybe other paths to obtaining the
item e.g. golden scarabs come from different chests each which have a different Loot Table
Stacked Deck (from Large Stockpile, Level 40)
The starting Loot Table for a Large Stockpile is ContainerLootLarge.
The entry to hit is ContainerLootLargeExtra, this has range of 75,000 however there is ceiling to
the entry since it is an AND table e.g. 88,000 hits the next entry, but will process all entries below.
The table is ClampMax so the first roll therefore needs to be greater or equal to 75,000..100,000
(25% chance).
The ContainerLootLargeExtra has a ContainerTrophyArtifcats bucket with a 99,500 (0.5%).
The table is AddToRoll so with 50% luck the range is Random(5,000 to 105,000) > 99,500 (5.5%)
The ContainerTrophyArtifcats has 23 items, however 10 of these require a level 56+ stockpile and
this is level 40. Therefore there are 13 items that apply so the chance of the Stacked Deck is 7.7%.
With 50% luck the odds of a Stacked Deck from a level36 to 55 Large Stockpile are therefore
25% * 5.5% * 7.7% => 0.106%
Of course the chance of any trophy mat is much higher.
