I received this late last night, and it gives us some insight on Tau playtesting that is going on at the moment. Everything from a Tau Dreadknight type walker to a new Kroot Huge Monster is here.Please remember that these are playtest rumors.I have been seeing a lot of play testing for the tau empire and have seen some new models as well. They look so new and epic it makes me really excited. Now I did my hands on some rules and names for units, If you are to pass these on then PLEASE send it to only reliable rumour sites.I will start with the new sky ray orbital blast ability. From what I can remember on top of my head is that the sky ray has to forgo his full turn of shooting for a single unlimited range blast that is:strength X AP 3 (wound on 2+,plasma corrosion, blast)plasma corrosion - any enemy model hit under the blast rolls a d6 every turn for the remainder of the game on a roll of 1-3 the unit or model suffers d6 strength 4 AP5 hits. On a roll of 4-5 the unit suffers 2d6 strength 5 AP 4 hits. On a roll of a 6 the unit is hit with 2d6 strength 6 AP 2 hits with the blind special rule. (these are test rules and subject to change)Tau fire warriors will have the OPTION to upgrade their tau fire warriors to bs 4 (I put option in bold to show it is an option for all those fluffy players)I believe the upgrade at the moment is being called 'advance training'battle suits are getting/got new models but have the same profile as now with the inclusion of an option to make them toughness 5 (cost or name is unknown)The kroot is getting a HUGE monster that looks like something from fantasy. It has kroot riding it but is under going constant rule changes due to either dying to quickly or for lack of usage. From what I remember seeing it has 5 wounds but only a 5+ save and was over priced IMO.kroot gain furious charge and move through cover and start with a 6+ save that can be upgraded to 5+ with shaper for an additional 2pts per model (making them 8pts per model) - remember this could change!finally their is options to make all your battle suits have 2+ saves for 20pts per model - all war gear that is in the current codex has been reduced slightly.the tau dread knight walker rumours you have read are 100% TRUE - I have seen the concept art/profile and from the top of my memory it is something like this.WS BS S T W I A LD SV4 4 6 8 4 2 4 8 2+/4+I will not share rules because they were on the next page of document of which I did not see. I did see the points which were : 210ptsnote the points were highlighted in red marker which means they are subject to change at next play testing.
