Ahh, that’s where my issue was. I was trying to make it in the description. Odd that the the tags work in just the description, while the snippets only in the, well, snippet field. Intuitively you’d think they’d work in both. Thank  you for clearing that up for me. 

I'd love the ability to do this but I must be missing something because it simply spits back the exact snippet I wrote - {{maxhp}} - rather than the corresponding value.
