Heroes 5 – by Azmadon (Izmail).

Hello! During the development process, some questions arose: 1) "How can I change, to be more precise, the effect-aura of the Arcat Dragons?" (I'm interested in at least changing the color; I want to turn it into an Ice Dragon.) 2) "How possible is it to add my own aura to a creature model?" (Some creatures, like Ice Golems, would benefit from a frost aura or at least a chilling effect.) 3) "Adding an effect to a creature's attack" (for example, undead creatures have a Cryo-Reflect effect in the form of snowflakes; how can I apply it to a regular attack of a creature – an ice golem – as a special effect when it hits an enemy?) 4) If I understand correctly, to add special effects like a "flaming sword" during an attack and a fire trail/splash, do I need to work with the original animation? Can something like that be done quickly using the game's existing resources?
