Rules Customization

In Terrea, some of the d&d 5e rules have been changed. This arcticle is mostely for DM’s but feel free to read it if you want

Short rest and hit dice

Instead of overcomplicating the system with counting hit dice, the rules are simpler: once per day, during a short rest of no less than one hour, a character can roll the total amout of its hit dice and heal itself. There is no addiotional bonuses for that sum, such as said character level.

Spells

"Identify" and "detecte magic" function as the same spell.

Homebrew spells

Kif's rugatka - you summon a magical sling-shot, +1 to hit and dealing 1d8 magical damage.

Feats

Skillful – grants 2 proficiencies instead of 3.
Lucky – This is by far the most OP feat in the game. Instead of having 3 re-roll chances, lucky gives you only one per long rest.

Homebrew feats

Expertise – choose on skill or tool you are already proficient in, and gain expertise in it, as the trait of the rogue class – which means you doubl your proficiency bonus on that skill.
Silent caster – you know the spells you cast so well, that thinking of them is enough to cast them. you do not need to matter words anymore to cast spell, nor make gestures with your hands – no spell you cast require verbal (V) components or somatic (S) . This does not effect spells that obviously require one of those components (for example, "comman")
Bagless caster – you do not need neither your spell focus OR material components (M) to cast any spell in your roaster. You do need materials for more powerful magic if the book specify the price of said item is higher than 20 gold – cheaper than that is free.
