Fortified Position and "Gains" events / attachments.

They would loose that Gains as well - correct? Like in Tears of Lys , does the character attached loose Deadly when Fortified Position is in play?

Thanks!

(3.8) Gaining Abilities
If any card effect has the text "character
gains...," any ability (traits, keywords, icon
modifiers, or STR modifiers are not considered
abilities) following the word "gains" is considered
to now be a character ability. However,
that effect is not assumed to be a part of that
character's text box. Any effect that blanks a
card's text box is assumed to blank that card's
printed text box.

I was completely wrong - thank you.

Its unreal when your attachment heavy.
