Ham is a bit of an oddball when it comes to buff cards. He's one of the few cards that can buff the party's attack
with his main skill, sharing this distinction with the likes of Eru, Baphomet, and Aphrodite. Ham carves out his own niche
by buffing both attack and agility, easily being able to supply +2 to both with a single 15% subcard boost.
While this sounds like a fantastic deal there are some drawbacks, for starters he can only buff the party's attack and agility on straight+ which is often easier said than done. The other and possibly more dire drawback is that Ham has a chance of inflicting a defense debuff on you, and while the chance of getting and amount the debuff actually inflicts decreases with skill level most players
That isn't to say you can't work around said debuff however as there are several subcard options to negate defense debuffs.
Since he does have the ability to spread on straight+ he has the option to subcard Xebec, giving the party an additional +1defense and canceling out the potential debuff in the process. Diamond would also be an acceptable substitute whilealso providing the 15% boost neccisary to push Ham to +2 on his main buffs, although her buff is a tossup between agility
and defense while also requiring a straight or better to activate.
In short Ham is most certainly a card that won't be on many players wishlists. While the attack boost is certainly noticeable
the agility boost is a bit less so unless you're planning on using cards with low hitrates or enjoy having a chance to
dodge enemy attacks. If either of those fit your criteria however, Ham is your pig-man.
As noted, Sl7 is extremely important- Allowing you to hit +2 on both stats with a +15%, reducing the debuff to levels negatable by Xebec or Diamond and only 40%, and looking like far less of a complete scrub, beyond running Ham. Noted, this attack also shifts to AOE on straight+, buffing the entire team and spreading all effects .
can actually work in your favor if you have Ham equipped to a non-attacking card however as it will leave any potential
skill links available for your teams attacking cards, oddly enough this also makes Ham a suitable subcard for himself. In the end it's up to you to decide if the relatively low activation rate is worth losing out on a potentially more powerful link.
