Devastator

If this ship replaces one of its defense tokens (for example, using Captain Needa’s ability), its replaced defense token does not count as discarded.

If this ship recovers a discarded defense token, that token no longer counts as discarded.

This ship cannot spend a defense token as part of the cost of resolving an upgrade card’s effect unless that effect specifies that a defense token may be spent.

When a ship equipped with Devastator is attacking from its front hull zone and only for one attack, for each defense token that has been discarded from that ship, you may add 1 blue die to the attack pool.
Defense tokens that have been replaced (like Captain Needa) or were discarded and then recovered (like General Tagge), do not count as “discarded”.
Also this ship cannot spend a defense token as part of the cost of resolving an upgrade card’s effect unless that effect specifies that a defense token may be spent. (Example, Darth Vader, Intel Officer, etc)

Intel Officer allows you to target your own defense tokens on the ship it is equipped too. The use for this largely benefits Darth Vader and Devastator.
