# Description

<!--
Explain this PR in as much detail as applicable

Some example prompts to consider:
How might this affect the game? The codebase?
What might be some alternatives to this?
How/Who does this benefit/hurt [the game/codebase]?
-->

This PR adds the Magmantle, a mantle that functions like magboots, but
slightly worse (like 15% more slowdown, but it does provide 20%
temperature protection like winter boots or scarves). Its intended for
species without the feet slot, which are harpy, diona and arachne. It is
available in the species tab of loadouts, for 6 points. Only Security,
Command, Dignitaries, Engineering, Salvies and Parameds can take it, if
they are a harpy, diona or arachne.

+  description: Invented by a dynamic duo of harpies, this mantle creates a localized gravity field, enabling the effects of magboots without the boot! However, the gravity field is cumbersome to move through, making the magnetic mantle somewhat inferior to its predecessor. However, it does come with a wool lining. Cozy!
