フル改造？ Trophy in Super Robot Taisen (PS3 & Vita)

[Full Remodeling?]
[Use enhancement items to upgrade the weapon stats of 1 unit to its maximum level.]

Missable!

You receive enhancement items as drops from enemies (by destroying or convincing) and they can be applied to your units in the Intermission menu. Keep upgrading one of the ?? [Weapon]'s stats for 1 unit until it reaches it's max value and the trophy should pop.

In the Intermission menu, enter the option ?????? [Power Up] (2nd option) > then you can choose which unit will receive the upgrades > then choose the enhancement items that upgrade one of the ?? [Weapon]'s stats (you cannot upgrade every Weapon stat for a unit. Each one has their types of attacks and only the items relative to their types of attacks will be possible to enhance).

Note that most of the enhancement items for weapons you get have an Plus ("+") mark at the end, which means the enhancement only works for 5 stages. So a good tip is to not use them before stage 7 and from there onward the enhancement stats will work until the final stage.

Other thing to mention is that your items do not carry over between your campaign playthroughs, so there is no point in sparing them for Campaign 2 for example.
