## Shield

# Notes:
# Temporary character attribute "Shielding"; there is a Land.MaxShielding.
# Land max is 9 in the current db.
# Visible via command 'show effects' as "Total Shielding = <value>".
# Value is subtracted from armor class for ranged attacks, half for melee.

Scenario: Temporary shield potion increases shield temporarily
  Given I use the "minimal" database as-is
  And I add player and character "TestTS02"
  And I create a "shield" potion of amount "5" and duration "2"
  And I put the item in the character's left hand
  And I start the server and play
  And I have a shielding of "0"
  When I open and drink "bottle"
  Then I have a shielding of "5"
  And I rest
  And I have a shielding of "0"

Scenario: Temporary shield potion maxes out at Land max
  Given I use the "minimal" database as-is
  And I add player and character "TestTS03"
  And I create a "shield" potion of amount "10" and duration "2"
  And I put the item in the character's left hand
  And I start the server and play
  And I have a shielding of "0"
  When I open and drink "bottle"
  Then I have a shielding of "9"
  And I rest
  And I have a shielding of "0"

Rather than starting a fight, I’m just using the “show effects” command to see what the effect is. Everything works well until I try multiple potions on a whim, and instead of combining or overriding, the effect drops to zero..? Couldn’t immediately figure it out, so tag the test and move on.

Scenario: Multiple temporary shield potions
  Given I use the "minimal" database as-is
  And I add player and character "TestTS04"
  And I create a "shield" potion of amount "6" and duration "99"
  And I put the item in the character's right hand
  And I create a "shield" potion of amount "9" and duration "99"
  And I put the item in the character's left hand

## Resistance and Protection effects
# TODO - verify no unintended resistance/protection
Scenario Outline: Resistance and protection potions have desired effects
  Given I use the "minimal" database as-is
  And I add player and character "TestRP01"
  And I create an "<effect>" potion of amount "<amt>" and duration "3"
  And I put the item in the character's left hand
  And I start the server and play
  And I have a "<resist>" resistance of "0"
  And I have a "<protect>" protection of "0"
  When I open and drink "bottle"
  And I have a "<resist>" resistance of "<resistamt>"
  And I have a "<protect>" protection of "<protectamt>"
  And I rest
  And I have a "<resist>" resistance of "0"
  And I have a "<protect>" protection of "0"
Examples:
| effect                         | amt | resist    | resistamt | protect | protectamt |
| Protection_from_Fire           | 2   | Fire      | 1         | Fire    | 2          |
| Protection_from_Cold           | 3   | Ice       | 1         | Ice     | 3          |
| Protection_from_Fire_and_Ice   | 4   | Fire      | 1         | Fire    | 4          |
| Protection_from_Fire_and_Ice   | 5   | Ice       | 1         | Ice     | 5          |
| Protection_from_Poison         | 6   | Poison    | 1         | Poison  | 6          |
| Protection_from_Stun_and_Death | 8   | Death     | 1         | Death   | 8          |
| Protection_from_Stun_and_Death | 9   | Stun      | 1 | | |
| Protection_from_Blind_and_Fear | 7   | Blind     | 1 | | |
| Protection_from_Blind_and_Fear | 8   | Fear      | 1 | | |
| Resist_Fear                    | 7   | Fear      | 1 | | |
| Resist_Blind                   | 0   | Blind     | 1 | | |
| Resist_Stun                    | 5   | Stun      | 1 | | |
| Resist_Lightning               | 0   | Lightning | 1 | | |

Resist_Death seems to have an interesting issue. In CreateCharacterEffect:

DragonsSpine/GameSystems/Effects/Effect.cs

GitLab

807
808
809


  case EffectType.Resist_Death:
    target.DeathResistance++;
    break;

But in StopCharacterEffect:

DragonsSpine/GameSystems/Effects/Effect.cs

GitLab

537
538
539


  case EffectType.Resist_Death:
    this.target.DeathProtection -= effectAmount;
    break;

So we’ll split that off into a separate test and bug-tag it until it’s fixed:

# bug? - Resist_Death adds death resistance but removes death protection when it wears off
# NOTE: Merge with other test when fixed.
@bug
Scenario Outline: Death resistance potion has desired effect
  Given I use the "minimal" database as-is
  And I add player and character "TestRP02"
  And I create an "<effect>" potion of amount "<amt>" and duration "3"
  And I put the item in the character's left hand
  And I start the server and play
  And I have a "<resist>" resistance of "0"
  And I have a "<protect>" protection of "0"
  When I open and drink "bottle"
  And I have a "<resist>" resistance of "<resistamt>"
  And I have a "<protect>" protection of "<protectamt>"
  And I rest
  And I have a "<resist>" resistance of "0"
  And I have a "<protect>" protection of "0"
Examples:
| effect                         | amt | resist    | resistamt | protect | protectamt |
| Resist_Death                   | 3   | Death     | 1 | | |

Zonk?

I initially skipped over it; what the heck is Resist_Zonk?

In the DoDamage method, we find:

 if (target.Stunned <= 0 && critical && !target.immuneStun)
  {
    int saveMod = -(target.ZonkResistance);
    // damager used a bash
    if (damager.CommandType == Command.CommandType.Bash)
    {
      saveMod += Math.Max(target.Level, Skills.GetSkillLevel(damager.GetSkillExperience(Globals.eSkillType.Bash))) -
        Math.Min(target.Level, Skills.GetSkillLevel(damager.GetSkillExperience(Globals.eSkillType.Bash)));
    }
    
    if (!DND_GetSavingThrow(target, SavingThrow.PetrificationPolymorph, saveMod))
    {
      // stun for 1 round if bash save failed, 1 - 2 for others
      if (damager.CommandType == Command.CommandType.Bash)
        target.Stunned = 1;
      else target.Stunned += (short)RollD(1, 2);

It also partially protects from spell-based stuns. But then what does StunResistance do?

  case "stun":
    #region Immune to Stun
    if (target.immuneStun)
    {
      if (caster != null)
      {
        if (target.race != "")
        {
          caster.WriteToDisplay(target.Name + " is immune to stun based magic.");
        }
        else
        {
          caster.WriteToDisplay("The " + target.Name + " is immune to stun based magic.");
        }
      }
      return 0;
    }
    #endregion
    else if (DND_GetSavingThrow(target, savingThrow, -(target.StunResistance) + casterSL))
    {
      if (caster != null)
      {
        if (target.race != "")
        {
          caster.WriteToDisplay(target.Name + " resists your Stun spell.");
        }
        else
        {
          caster.WriteToDisplay("The " + target.Name + " resists your Stun spell.");
        }

So StunResistance is just for a “stun” spell, and ZonkResistance is for all other ways you might get stunned. Interesting. I guess I should add a test for ZonkResistance.

…which fails. Turns out it’s an effect for worn items only, even if I make a potion for it. I’ll have to tackle the worn effect thing, once I’ve exhausted all the potioning. Tomorrow.
