Reptiles are your own NFT pets in reptillium. As long as the player keeps the reptile well feed and healthy, it will continue to produce RPLM tokens for the player. Each reptile has its own stake power, = RPLM/ Day. After producing tokens for 3 DAYS the reptile has to be fed LFOOD according to its requirement.
After the reptile is fed, only then it continues to produce RPLM for the players. Reptiles can be leveled up using excessive LFOOD player has generated to increase RPLM output. On levelling up, the reptile will have increased stake power as well as LFOOD requirements.
