Editing Warhammer 40,000/9th Edition Tactics/Thousand Sons (section)

===Getting Started===

The Thousand Sons were one of the middle releases of 8th edition, and experience has shown this to have been a negative rather than a positive. Now, in 9th edition, the army has received some updates to match the other 9th edition codices. You should get your hands on the following in the listed order:
====Main Books====
These are your necessary books that you need to even start playing the army.
*'''Codex Thousand Sons''': Released in Aug 2021, this book contains the main bulk rules of your army, the faction's core book.
*'''The Most Recent FAQ and Errata''': For rules clarification and fixes. [https://www.warhammer-community.com/wp-content/uploads/2019/09/djrQBhGf6Lkf78BE.pdf '''Here''']

====Supplements====
Should you wish for more units beyond the codex or wish to ally with other Chaos armies, these could be on your radar. Do keep in mind that allying in units from a codex other than yours takes away Cabalistic Rituals and possibly more bonuses away depending on how you build the army.
*'''Imperial Armour Compendium''': For all your Forge World needs, with its subsequent [https://www.warhammer-community.com/wp-content/uploads/2020/12/TG5TwX0VYl8BM5pK.pdf '''FAQ'''].'''
*'''Codex Chaos Space Marines, Version 2''': Released in April 2019. Allows you to Ally in some CSM and their toys.
*'''Codex Chaos Daemons''': Should you wish to add in some daemons.
*'''Codex Chaos Knights''': You ever want a big stompy robot to join your guys? This is the book for that. 
** Further rules for CSM, Daemons, and Chaos Knights can be found in Warzone Charadon Act 2 and Engine War.
*[https://www.warhammer-community.com/wp-content/uploads/2019/12/25553ac3.pdf '''Thousand Sons: Legends PDF''']: For 'Legacy Units' and Wargear options (eg. Combi-Plasma's and force axes on the non-terminator sorcerer.)

====Boxes====
Boxes, boxes, boxes! Currently there <s>are two sets</s> is one set that you can buy to make ok-ish savings compared to purchasing the kits individually.
*'''Start Collecting: Thousand Sons:''' A good launching off platform for new players. Contains Ahriman (weird for a named character but there's not much else), 1 unit of 10 Rubric Marines, 1 unit of 10 Tzaangors, and 2 Tzaangor upgrade kits, in case you want them to have the chainswords and pistols (you don't). '''No longer in production.'''
*'''Combat Patrol: Thousand Sons:'''  A box containing the Infernal Master, 5 Scarab Occult Terminators and a lot of Tzaangors at 20 of them. An alright set, but you're gonna want more than just that, consider it an addition to the Star Collecting Thousand Sons box.
**Alternate Opinion: You can take one unit of Tzaangors for each Rubric/Scarab, and no more than that; this box comes with 20, so it's only good value if you're going to max out this one unit, or devote yourself to an army of Birdmen. The Infernal Master, like a lot of the "box exclusive HQs" are <s>kinda trash and gimmicky</s> tricky but potent, has brutal debuffs, a Cabal/self psychic test booster, and longer ranges for the two buffs it DOES have. Buying a Demon Prince and Scarabs separately is cheaper and more useful.
**Secondary Alternate Opinion: This is a pretty potent start for a Thousand Sons army. '''Infernal Masters''' are brutal force multipliers thanks to just having Malefic Maelstrom and Glimpse of Eternity, and Scarab Occults are the backbone of most Thousand Sons armies. While you can only use one 20 man unit of Tzaangors from this box, the Tzaangors themselves are at least usable. If you are in need of Tzaangors (especially with the Warpmeld Army of Renown for them), a unit of Scarab Occults and an Infernal Master, there's worse you can do. Besides, nothing stops you from [[Proxy|just using the Infernal Master as a fancier Sorcerer.]]
