I have done a good deal of work towards a second version of the VSRD to add more content and alter some of the numbers. Before I finalize anything, I have some potential changes I'd like opinions on.<br/><br/>- Changing the stomach AC calculation from "12 + Constitution modifier" to "12 + proficiency bonus + Constitution modifier" for player characters only. Adding monsters' proficiency mods would be pretty intense as they scale higher than the player version. This change should make players have tougher stomachs as well as make the Constitution stat less important. Keep in mind that a swallowed creature is considered restrained and therefore has disadvantage on attack rolls. A level one character's maximum stomach AC is 17. Assuming a monster has a +3 to hit, the monster has only a 12% chance to actually hit. Assuming a +7 to hit only raises those odds to 30%. Disadvantage is powerful!<br/>- Changing the amount of damage prey has to do to a stomach in one turn from "1/10th health total + Constitution modifier (minimum 1)" to "5x Proficiency bonus + Constitution modifier" for player characters only. Keep in mind that this damage must be dealt using a light slashing or piercing weapon. This means that a 1st level character would have a 10 hit point threshold (minimum) and would be more likely to die than to heave up their prey, but the threshold would scale upward, reaching 30 (minimum) at level 17. This change combined with the disadvantage and the fact that taking this much damage does not force you to immediately release the prey (as it forces you to make a Constitution save to avoid releasing the prey) should hopefully balance things out a bit.<br/>- Changing the struggle action to also give resistance to digestion damage on a success in order to help balance out the raised challenge of escaping through attacks. At least you can attempt to debuff your predator and halve the damage you take in the process.<br/><br/>Another question I wished to pose was how in the world do you handle goo-creatures? Do they wear normal armor and weapons? Do they use special, goo armor and goo weapons? If the latter, do those prevent easy-absorption of prey?<br/><br/>I was trying to find a way to adapt the goo-based feats of the Pathfinder VSRD, but have run into trouble with the logistics of how a goo-creature works.<br/><br/>I am still considering making digestion damage scale faster or raising the damage overall, but am not convinced it is necessary. A tenth level character can do 4d8 + Strength or Constitution mod (likely +3 at this point) (average 21) damage to all creatures currently in its stomach in addition to its normal actions. They also have the ability to take the digest action and inflict that damage again, allowing for 8d8 + 6 (average 42) damage to possibly multiple eaten creatures.<br/><br/>A level 10 Barbarian's action economy choices look like this (Assuming Strength 16, no feats):<br/>- Option 1: Make two attacks at a +7 bonus for 1d12 + 3 damage each (without rage). Make two additional attacks. Assuming these attacks all hit, they deal an average of 38 damage total.<br/>- Option 2: Attempt to grapple a target and ingest them on the first turn. Attempt to swallow on the second turn and make an attack against another target using the profile above. Assuming this is all successful, the swallowed creature takes an average of 21 damage and another target takes 9.5 damage.<br/><br/>From turn three onward, the Barbarian automatically deals an average of 21 damage to the swallowed target and can continue dealing 19 average damage to another creature. This is in addition to the control effects of having a creature swallowed, which is particularly devastating to spell-casters. That said, the Barbarian missed out on an average of 7.5 damage across the first two turns by taking option 2, but it would only take a single turn to make up almost three times that lost damage.<br/><br/>This is, however, assuming that all of the Strength (Athletics) checks were successful to eat the target, which is far from a given, but even partially succeeding at these checks is applying some control effects to the target.  That is also assuming a lack of feats, which could change the action economy of that a bit.<br/><br/>Thoughts, anyone?
