Currently, the Monster template is only capable of showing one Tier version of a monster. Way back in June '11 I attempted to remedy this but abandoned the effort after some difficulties with the template and completely forgot about it until now.
I've set up a proof of concept for a new version of the template at http://wiki.spiralknights.com/Sandbox
We have three options here:
1: Leave the current Monster template as it is.
2: Update the Monster template to show three tier versions, and make separate templates for monsters that only have one or two versions.
3: Update the Monster template with the ability to be customized with additional images and changeable Tier text - the same template could be used for all monsters, with settings for how many images to show as well as the text above them. In my opinion, this is the ideal option, but I would probably need someone good with templates to help out.
If anybody has any objections or input regarding the matter, please say so here. If nobody has a problem with it, I will go ahead and attempt to implement option 3.
I managed to get option 3 implemented and working. The new settings are very hack-ish, so I will explain them here.
|tier1=
|tier2=
|tier3=
Add these options to customize the text over the pictures. You shouldn't need to add these unless the monster only has one version, as it will label them as Tier 1, Tier 2, and Tier 3 by default.
|image1=
|image2=
|image3=
Add these options as "switches" to disable the respective image. Do not add any text after the = if you want to disable the image. More complicated things can be done with these options, such as images that use nonstandard names, but there's currently no need for that.
If you have any questions, or if the new template causes any problems, please let me know.
