I keep forgetting to upload this so here it is. Use h4perlay as the trigger word d for the whole Lora (so always include it), and then include one of the sizing options: h4permax h4peregg, h4geegg, n4rmalegg and sm4llegg to get the right egg size.

This Lora is trained on a lot of BIG eggs. To get bigger eggs, it helps to include related e621-style tags in addition to the keywords. On their own, the keywords tend to produce smaller eggs than hyper eggs.
