Some one mentioned equipping the Shield of Seals in a moveset. Not sure if it could be tricky to implant in the context of Smash, though I'm sure it can be done right... Though I don't really know myself, here are some ideas:
- Have the shield work like Link's. Wherever the shield's static position is, it will have a hitbox. The shield will block most projectiles if hit. Perhaps Chrom can also block attacks when moving and in the air
- Have the ability to bring out the shield during any attack/combo/whatever without any lag to block incoming attacks. Don't know how that will turn out...
- Have the Shield of Seals literally be Chrom's Shield, similar to how Yoshi has his own special shield. Chrom will bring out the shield in front of him as it glows. The shield "bubble" will look more distinguished, and the shield itself will have higher defences, causing the shield to not shrink. This prevents shield stabbing/poking and the shield could also have a faster restore time. Perhaps Chrom won't get stunned when the shield happens to get shattered, but just being unable to shield until the normal duration of the stun time is over (a few seconds). Of course this needs to be balanced, though I'm really not fond of the idea of not being able to jump out of shielding...
