SCP-2398 is a baseball bat that has the effect of upon hitting something, it causes an explosion. The size of the explosion varies upon what is being hit, e.g. hitting a cow caused a larger explosion than hitting a chicken. The explosion can also lead to the operator being damaged unintentionally, so testing of SCP-2398 has discontinued.
I suggest 2 ways it could be implemented:
1.): The simpler implementation. Upon hitting someone, it deals 75 explosive damage and causes a explosion. The explosion does not have an AOE and is only visual. It would also fling the target far away, so it can be used to get someone away from you.
2.): The more complex implementation. Similar to variation #1, it deals explosive damage and causes a explosion. The explosion also does not have an AOE and is only visual. The amount of explosive damage is dealt to the target and the user scales on how much max health the target has. The target gets flung far away, but the distance does not scale on the target's health. Here's a list of suggested values for it:
≤100 HP: 75 damage is dealt. 0 self-damage.
101-499 HP: 100 damage is dealt. 10 self-damage.
500-999 HP: 150 damage is dealt. 15 self-damage.
1000-1999 HP: 200 damage is dealt. 20 self-damage.
≥2000 HP: 250 damage is dealt. 25 self-damage.
SCP-2398 takes the slot of the Stun-Stick / Crowbar, and is intended to be used as a melee weapon. To make up for its strong damage and flinging capabilities, it would have a slow attack rate.
SCP-2398 spawns anywhere SCP-268 and SCP-512 can.
For the model, I suggest that the Baseball Bat from L4D2 be used as the base. A port of it to GMOD can be found here: https://steamcommunity.com/sharedfiles/filedetails/?id=883508806
