Spending a power counter from IT Department creates a constant ability that checks how many power counters are left on IT Department each time a power counter is spent. If you spend multiple power counters (either to boost the strength of a single piece of ice multiple times or to boost the strength of multiple pieces of ice), then each time a power counter is spent IT Department "updates" the boosted strength according to how many power counters are left on IT Department as of the last spent power counter.

## Controversy[]

On December 29, 2014, Steve Lyman asked Lukas on Twitter how IT Department is supposed to work. The first answer Lukas gave was incorrect and caused a large uproar on Twitter as people struggled to understand.^{[1]} but due to the contradiction with the first tweet it was lost in the sea of tweets.

The following day, Lukas apologized and gave a more direct and correct response on how IT Department is intended to work. See the rest of the Twitter thread to read more about the misunderstanding.

## Steve Lyman's Question[]

3 counter IT Dept. Is it: -2 counters = +5 strength (3+2), or -2 counters = +3 strength (3 counters on ITD incl. those removed)?

### Lukas's Revised Answer^{[2]}[]

## Laury Plant's Question^{[3]}[]

I'm still misunderstanding, how is this 18 and not 19? Rechecking past resolved events and modifying them in retrospect?

### Answer^{[4]}[]

## Ben Blum's Question[]

What happens to existing ice buffs when ITD is trashed? Each gives +1+0 str or what?

### Answer^{[5]}[]

## Usage Examples[]

Suppose there are 5 power counters on IT Department. Spending 1 power counter would boost the ice strength by 1 + (4 power counters remaining) = 5 strength. Suppose you then spend another power counter. First, the previously-spent power counter would update its strength since the number of power counters on IT Department changed, so that it is now 1 + (3 power counters remaining) = 4 strength, and the just-spent power counter would add its strength to the first strength boost: 1 + (3 power counters remaining) = 4 strength, for a total of 8 strength added to the chosen ice.

The progression for spending power counters from an IT Department with 5 power counters would be as follows:

**1 counter spent**: (1 spent + 4 remaining) =**+5 strength total****2 counters spent**: (1 spent + 3 remaining) + (1 spent + 3 remaining) =**+8 strength total****3 counters spent**: (1 spent + 2 remaining) + (1 spent + 2 remaining) + (1 spent + 2 remaining) =**+9 strength total****4 counters spent**: (1 spent + 1 remaining) + (1 spent + 1 remaining) + (1 spent + 1 remaining) + (1 spent + 1 remaining) =**+8 strength total****5 counters spent**: (1 spent + 0 remaining) + (1 spent + 0 remaining) + (1 spent + 0 remaining) + (1 spent + 0 remaining) + (1 spent + 0 remaining) =**+5 strength total**

Thus, it is optimal to spend half of the power counters, rounded up, to get the highest boost to ice strength.
