 How to Acquire Shield

Shield Tips & Notes

  • Shield is a very strong spell and is always beneficial to sacrifice a spell slot for it whenever you are about to get hit a strong melee attack, as a reaction increase your AC by 5 till your next turn and make you completely immune to Magic Missiles, because of this, it is important to set your Attack of Opportunity reaction to either disabled or "ask" as you, your allies and your enemies only have one that replenishes when their turn comes.
  • AI enemies increase in difficult by beginning to likely prioritize easier to hit targets with lower health than the closest target to them, in Tactician Mode this is the case from the beginning to the end of the game. Because of this, if your Wizard/Sorcerer have higher health that contest other Playable Characters and higher AC than them, they are unlikely to be selected as a target by the AI to attack, when you cast Shield this will cause the enemy to prioritize other targets to avoid constantly missing.
  • Shield can also be found on some items that can be used once per Long Rest and can be casted by anyone who wear it as a reaction, AC can scale really high in the later acts of 2 and 3 up to 21-23 AC, and increasing it to 26-28 makes you downright impossible, especially if you are the only valid target to hit thanks to either you allies hiding or have Sanctuary applied to them and on top of applying Disadvantages on the enemy in other means.

      Has anyone tried using this with the Extend Spell metamagic? Curious if that can be applied to make it last 2 rounds.

        So this is currently not blocking Magic missiles at all for me. A certain endgame fight with some magic missile spamming bastards were still annihilating me with shield up.

          Blur seems like the better spell if you have nothing else to concentrate on. This uses 1 spell slot and can only protect you from 1 hit. Blur lasts for 10 turns as long as you can maintain concentration. That's a ton of disadvantage checks for enemies.

            Great spell to have on Eldritch Knight or Abjuration Wizard. Or if you’re real nutty, multiclass the two together! Arcane Ward makes for decent early tanking.

              What I'm currently seeing is that if shield is set to use either a level 1 or 2 spellslot for reaction, but say level 2 spell slots are depleted it doesn't even pop-up unless you've gone into the reaction tab and removed lvl2 slots once they were empty. Frankly an insanely stupid amount of micromanagement and totally unnecessary oversight.

                This is one time reaction buff? (Used at once?)
                Or this buff can trigger reaction every time when you get a hit? Until long rest.

                  Continue from comment below. It only popped up if the attack was already going to miss. If it was going to hit, it did nothing. Basically they flipped a bit somewhere and got the effect backwards.

                  Those who say this skills work doesn't have the sense to do their own testing or is hallucinating the whole mechanism wrongly.

                    similar with warding flare. "pre attack rolls reactions" are useless due to how reactions calculation work.
                    the game consider the attacker attack roll vs your initial AC (pre-shield application) first before allowing the warding flare or shield kick in. if the attack roll is higher than your initial AC, these reactions will not kick in; vice versa.
                    EG 1: ur AC is 20. attcker roll 21. you will get hit. no reaction from defensive reactions like increase ur AC and give disadvantage to ur attacker.

                    EG 2: ur AC is 20. attacker roll 19. you will not get hit. reaction kick in from defensive reactions like increase ur AC and give disadvantage to ur attacker.

                    due to EG2. these skills are useless. waste.

                    Diff case for "post attack roll reactions" like missile snaring, wrath of storm since they reduce dmg or shot back at ur attacker after they roll their attack.

                      Strongest 1st lvl spell for the lategame. Even if it manages to block 1 attack, the value is massive, as enemies hit for 25+ dmg. Both of my casters run it and I use the shield amulet for barbarian.

                        Found the necklace that grants the Shield Spell; it is called the "Amulet of the Harpers", and it is sold by Quartermaster Talli at the Last Light Inn, on Act 2.
