Yes, Defense is calculated with your base score of 10+CON+LOOT. Feasibly, you could get up to those high numbers (I’ve seen and played characters whose DEFENSE started at 17+ right off character creation. It does seem like much, but it’s possible and it’s a play-style that some people like and fits with some characters.
PLAYER - “I want my guy to just be rock solid out on the field! Nothing is going to get through his Armor.”
GM - “Sick! That’s awesome!”
What this means though is that encounter escalation becomes more poignant for this character. Sure, no mook is going to get through that armor unless they have a really lucky shot, but what about the big bad? He’s got +8 to hit and one of his abilities makes you roll DEX to avoid damage. Since you’re wearing all that ARMOR, DEX is always HARD. Now we’re talking some really crucial dice rolls.
A GM’s job is to provide problems that players need to solve. If a player has put all of their eggs in the armor basket, they’ll be really good at solving problems that require armor, but less so in other situations. That’s the player’s choice and it’s awesome, but that choice comes with consequences.
As for rolling DEFENSE, you can absolutely have player-facing rolls in combat. As you said, players would just roll a 1d20+DEFENSE and try to meet or beat the target whenever an enemy tries to hit them. It works, but @Alex actually mentioned some things to be aware of on the ICRPG Facebook page yesterday, if you’re consider doing player-facing rolls in combat:
“…The other piece you lose as a DM is the ability to adjust enemy to-hit bonuses as one of your DM tools. In terms of your challenge tuning, then your sole dial to adjust becomes the room target. I don’t like giving up that flexibility.
When you switch to player facing, then your whole game becomes all-saving-throws-all-the-time, which I have found tends to become a bit monotonous. Conversely, with normal DM rolling, you have two tools to challenge players: enemies that have to roll to hit for damage and saving throws to avoid damage.
Finally, as someone else mentioned, there is always the limbic hit. Some groups vastly prefer the DM and monsters rolls as a force acting against them versus, “oh crap, I rolled low and now I am taking damage.” Its subtle, but it can be a buzz killer in a game. Plus, as a DM, I am a player too, so I like rolling dice and being a part of the action, and I don’t want to give that up.
So, to answer your question, those are the main things that “break” when you use player facing rolls. Some groups really like it, but I don’t usually recommend it to DMs.” – Post Link Citation (you may have to join the Facebook Group if you haven’t already).
