1) Choose any item in the game that has the Playable switch. These are essentially clothing and weapons. Most favored choice seems to be a ring but it really doesn't matter since it's 3D object will never see the light of day. In fact a base model marked unplayable cannot be placed in game. | 1) Choose any item in the game that has the Playable switch. These are essentially clothing and weapons.

2) Copy your choice by saving with a new unique ID. You probably want to use the actual name as a comment as to what the token effect will do, etc. | 2) Copy your choice by saving with a new unique ID.

1) Tokens are always specific to the actor they are applied to, even if that actor was created by PlaceAtMe. In contrast, spells and abilities are added to the base model. (All [new] actor references of the same base model inherit these effects when they respawn.) | 1) Tokens are always specific to the actor they are applied to, even if that actor was created by PlaceAtMe.

2) Local variables are persistant. Scripted spell effects and abilities reset when the actor comes into scope (same cell) as the player, meaning any local variables are re-instantiated (to 0). | 2) Local variables are persistant.

5) When [the marked actor is] in scope the GameMode block activates every frame. When out of scope the GameMode block triggers about every 30 seconds or whenever the player moves to a new cell. Additionally it will always fire when the token is first added - meaning that you have an effective OnAdd method. | 5) When [the marked actor is] in scope the GameMode block activates every frame.

Note in this example you may be able to do the AddSpell directly from the quest script. However, often you may need to add things multiple times or the particular commands may not work until the actor is in scope - hence the GetInSameCell conditional. Conditionals and global variables are often needed to ensure the timing of when token effects are triggered. | Note in this example you may be able to do the AddSpell directly from the quest script.

ASIDE: This works equally well for basic items, etc. However, much of the time you want to introduce a persistant scripted item in to the game. This is a bit more tricky since objects easily lose their scripts when being moved from 3D (the world) to 2D (an inventory/container). To do this firstly it is a good idea to have a room of your own to hold stuff, even if you can never get to this area from inside the game. The reason is by doing this you will never cause mod conflicts. You then need to (1) MyObject.MoveTo player (2) MyObject.Activate player (3) MyObject.RemoveMe <VendorHiddenContainer>. These 3 steps must be done in different (successive) frames. A (hidden) vendor container should be used. If you add directly to the vendor, 9/10 times you can bet that vendor will equip this item immediately - and not let go. (This is handy if you require the item to be pick-pocketed.) | ASIDE: This works equally well for basic items, etc. However, much of the time you want to introduce a persistant scripted item in to the game.
