The "Heal Conditions" field is there just to note things like Fast Healing and Regeneration. It's only shown for NPC/Monster and does not impact the sheet other than noting the monster's ability. Translations; once on Crowdin/Roll20, you'll filter roll20's project by language (Polish), then you can pick a specific sheet to translate. You can further filter a given sheet by incomplete translations, completed translations, or all. Make your translation changes and submit for approval. I'm not sure what the approval process/requirements actually are, but once approved, the translation changes will be submitted to roll20's character sheet repository to be merged into production. Merges "usually" happen on Tuesday and Thursday.
