yeah, misread shards as shields.

one final piece of advice- the crumbling mechanic is pretty good, but i would only submit one of the three (creature, shield, or weapon) to the crucible, as if you submit all 3, it will probably have an adverse effect on the voting results for them. it is easy to see how the mechanic could be implemented into a variety of vessels, but the core idea of crumbling remains the same and that is likely what, if anything, will be 'inspiring' to zanz should he implement the idea in some form or fashion. so basically my advise boils down to not watering down the mechanic by making it into a series of sorts. zanz has shown that if he likes an idea enough, he can implement it in a variety of ways if he so chooses.
Good advice... although, wouldn't submitting the series make it easier for the community to vote on which version of the implementation they like most
E.g. It gives the community the chance to give feedback (via, voting, etc.) on whether they like the mechanic better as a weapon, shield, or creature?
This can give an important avenue for discussion which would provide useful feedback for Zanz.
Alternatively, you could post what you feel is your best one, but supply links to the others, and a poll at the top to let players voice there opinion that way.
That would also help keep from overcluttering the crucible polls.
